The EASIEST method to do taking away! How to do subtraction.

- This is the EASIEST way in the world to do subtraction!
They won't teach you this way in any UK state school (possibly not even in any UK independent school either) BUT they should!
Don't bother with the stupid number line method or the one where you cross out all the numbers and change them - that's CONFUSING!
Learn the '1 up 1 down' method and you'll be able to subtract ANYTHING really quickly! It is the easiest way and makes the commonly used method of borrowing or trading zeros seem so much harder!
This IS the EASIEST method for ANY subtraction! Works for any take-aways where the top number is larger than the bottom. Much better and less confusing than the decomposition or regrouping or trading zeros method (whatever you want to call it - who cares - it's rubbish).
Explained here: • Video
If you know how this works, please post a comment.
If you can do it - let me know how easy you found it!

Who does this method already?

Glad to see someone is still doing subtraction the old way, this is how they taught me in the 1970's and the way I showed my kids. This new method of crossing out and rewriting numbers is so messy. Took me a lot of wading through 'messy' videos to find one that uses the same method that I use.
Thanks!
The question now is: Can I rewrite my brain at age 38?
Now your 48 man geez

now you’re 49
Just shows man how time goes by just like that
Wow! I spent a lot of time at school scratching my head. Im 31 now and its finally all over. Thank you.
My daughter is having trouble doing some subtraction using the cross out method and I'm having trouble explaining it clearly to her. I showed her this and she got it in less than a couple of minutes. Just to make sure I gave her three fairly complicated subtractions to do and she knocked it out of the park... Thank you.
Davidos Foto glad it helped! Shame schools don't teach this method!
Yep, Well I've put a note in with her homework book for her teacher to read. It'll be interesting to see if any reply is made.
They teach this in Ireland now because when you get into the more complex maths this is less messy and easier to see versus the traditional borrowing method. Good stuff
Great! Lets hope the rest of the world catches up 😜
@@MrDarcy-OlMan Calculus, trig and geometry r all complex math... My former high school math teacher always called me a black leather cladded biker jock with a math IQ of 75.
Just sent this tutorial to a little kid who's having difficulty with subtraction!
Thanks for uploading this sir
Happy to help!
@@MrDarcy-OlMan SIR HELP ME IM SOO DUMB I CANT EVEN ANSWER A SIMPLE SUBSTRACTION
I am now going into the same battle with my daughters school as my mum did with mine. I waited until she was taught and understood the current method and then taught her this amazingly simple method that I have always used. Her first homework has just come home with all ticks for the answers, but they have crossed out all of her workings (nice little 1's) and scrawled the workings for the current method across it. We shoudl FIGHT for the '1 up 1 down' methods - providing the child knows WHY they are doing it...

US here. They don't do this, either. My mom taught me it to help me in the '70s. However, I like that she scratches out the lower numbers so it is CLEAR what she is NOW subtracting. To me, your 1-8 looks like an 18, instead of crossing out 8 and placing a 9 there (in the tens place). However, it's good to see someone else doing it. I've always been the "freak" including in school where they made me PROVE that this method worked. Even back then they didn't know what it was.
This is the method I was taught fifty years ago, the old English method. I still do my subtraction using this method.
Valerie Rawlins absolutely! It’s the best and easiest method so what’s the point in over complicating things like they do now.
@@MrDarcy-OlMan beats me. I live in the US and tried teaching my children this way and the old methods with long division, short division , long multiplication. My goodness, you would have thought that I was teaching them how to build a dirty bomb. Why is simplicity frowned upon in this manner??
Valerie Rawlins Schools think that the old methods are difficult for children to break apart to understand the methodology, so they invented new ways to help kids ‘see’ how a solution can be reached, but only people with a ‘maths brain’ get it anyway.
For those suggesting (like Peter Price) that this cannot be modelled with manipulatives, and that "borrow and pay back" is a confusing metaphor, here is how to teach it.
Call it "equal addition". The idea is that we are adding the same amount of units to both numbers, ten on the top and ten on the bottom. The ten on the top is then immediately decomposed into the next lower down unit. So it uses composition and decomposition, just like the other method, but it also adds in the concept of "adding equal amounts to the top and bottom number wont change the sum". This is probably a good idea to explore with your learners.
Finally an EASY method, thank you. From a student in the UK :-)
This is so much easier than our American way, when we barrow from the next number! 👍
I still think our way is more easier. But that is my opinion. This just reminds me of the common core being taught now.
im guessing its easier since that is how we learned it and we are used to it by now
Finally !!!!! someone with the traditional method..''.hallelujah''....I can't for the life of me work out how this seemingly new calculation appeared. Thought they were leading into integration by parts or something! ...well done mate..done well :-)
It was explained to me when I retrained as an adult, that the new method is essentially there to be idiot proof. To give the people who couldn't even grasp the basics a chance to have some fundamental maths skills. Personally I found it took something simple and made it confusing.
Many years ago after watching a maths teacher explain what I refer to as short division to a class of pupils, who sat there not apprehending the concept, I approached the teacher after class and showed him the simpler method, to which he replied that this is America and the 20 th century.
I was taught this method when I was at primary school. I am now 48. For some reason they now teach the squaring off method which is more confusing. I have to look up videos to help my kids now and I shake my head because I believe it is much more difficult.
This is better than regrouping because, 1: You don't cross out numbers. 2: It is faster.
This totally helped me i forgot how to do it then i watched this
before: ;-;
after: ^_^
When I was learning, I independently figured this method out. I didn't call it one-up-one-down, though I like that, and I actually changed the digit in the subtrahend rather than just writing a 1. My teacher didn't understand what I was doing and gave me lots of grief because I had a hard time doing the traditional borrowing, especially with 0's in the minuend, and couldn't write what she expected but "magically" came up with the right answer. Thanks for sharing!
awesome method I could never do subtractions until this video 👌😊took less then 10mins to learn. Do you have a method for addition?
Addition is easier, you just add numbers. With subtraction though I was rather confused because I ran into negative numbers when subtracting a bigger number away. This cleared it up for me :)
think he's pretty passionate about his method
I like ur picture bob ross...
Very interesting! This was the way I was taught in the 1960s in New Zealand public school. In fact I didn't know of any other method until I started helping my son, at which point I discovered the ridiculously convoluted method that apparently most people use. Your method is so simple! I sometimes use a variation where the 1 is explicitly added to the bottom digit before subtracting. Either way, it works because we are effectively increasing top and bottom by the same amount.
You were alive in the 1960s?
Yeah. Similar to adding a number to both sides of an equation. I’m your age. I was taught that way
Just having exactly this problem with my Granddaughter, her stupid teacher taught her the state approved method that only works easily with simple, carefully selected numbers, a fat lot of use that is in the real world!. As soon as she has to reduce a 0 by one and so reduce the next column as well she's lost. In some cases you have to change the numbers over and over again, how ridiculous. So I teach her this method, which I've always used, and she finds it very easy, but I know the idiot teacher is going to reject it because it's not done the way big brother dictates is MUST be done.
So now I have a dilemma, try to help her with such stupidity as the school insist on teaching, which is only leaving her afraid of maths, or teach her properly and she'll have to go through the conflict with teachers that I had right through my education about many such things. Teachers always have to be right, even when they're staggeringly wrong...
+Greg M I know; it's ridiculous! I'd speak to the teacher and stand up for whats right.
Totaly

wow!!!!!!!!!!! thanks works like a charm and youre right about UK schools!!
Yeah talk about my second grade teachers in America who tried to teach me to do it the last way that is shown on the video. OMg that is so annoying and confusing! I love this method! Its made studying for my math test so much easier!! :)
I actually saw this in an old textbook (Counting House Arithmetic, 1887), but he didn't explain it as clearly as you did. One up/one down is much simpler and quicker than the "borrow and carry" method that I learned in school. And it makes for neater work without all those crossed out numbers. Thanks!
Thanks You Helped A Lot With Subtracting. 🙂
THIS HELPED A LOT!
I really appreciate this life changing math tip that you've shown to many kids who had difficulty with subtracting.
destiny phongmany Thank you for the support! So much simpler than what schools teach now!
Its an awesome shortcut buts its just that, a shortcut. I find understanding the fundementals of why these methods work is more important.
I learned this method in a state school in Sydney, Australia in 1970. When we moved to South Australia later the same year they taught a different method. Their method was cumbersome and confusing. The old 1 up 1 down never let me down. Wake up educators...it's easier and simpler. Don't procrastinate...DO IT!
I was taught this at school in the 60's - so much easier than the way the kids are taught this in schools now.
Janet Pearce exactly!
Genius!! Have used other methods that confuse the hell out of me.... This is so simple
Literally, I was at work, went to subtract, couldn't remember a thing from school. (I know terrible but calculators have taken over for simplicity and ease at work - I'm only 25).
This method was so useful! So fast and easy! (albeit it took a little while to understand without headphones haha) Thank you!
+TheScottGordon Glad it helped!
Thank you so much. I used to know how to do this easy but I haven't done it for so ling I've forgotten.
Absolutely ! - My grown up children are still struggling with this "New Maths" rubbish.
You are showing the method that I learned when I was 8 years old and have used literally hundreds of thousands of time as a land surveyor in the time before calculators!
Thank you fro bringing some sense back into the world.
No problem! The old ways were the best ways!
@@MrDarcy-OlMan "old ways" like burning witches and flat Earth?
thanks!!!, you really help me out with subtract, now i never get confuse while subtracting.
Thanks for this ..... This was the way I was taught....... simple & straight forward.
I knew this would be the best .....because it is the shortest video on subtraction
It seems this is the state working deliberately to demoralise kids (?) for some reason ....perhaps so they readily accept they will never afford housing.
nixy49 Appreciate your comments thanks!
This method has been the simplest for me to understand, simplicity is key. Thanks mate
Interesting. Thanks!
Very clever and a big thank you
Wowwww...this helped me a lot and now I can subtract faster!😯😯😁
Rocky Sky glad it helped!! It’s the best method
THANK YOU THANK YOU THANK YOU! i have struggled with maths since i was a child....why did no one ever show me this method?
It works!!!! Yay, I'm a genius lol
this trick helped me a lot thank you
No problem - glad it helped!
Easier method then the way I was taught as a child. I love this way !! It's kind of like each row becomes an individual problem to solve but now with the higher number always at the top to make subtracting easier. Thanks!! Have a test to take at the school district for my new job and I needed an easier method!
Glad to see someone's still doing it the old way
genius
, put things into simple terms for this dummy, thank you
Thank you very much for replying happylambs. I'm always looking for an easy simple way of doing subtraction because I learnt the complicated way which to this day is still hard for me.
This has been a huge help! Best tip I have seen so far.
very helpful, thanks mate
Amazing method, but i've tried to figure out how that would work with negative numbers. Or what i should say is a smaller number, subtract a larger number. Say instead of 8004 - 3685, it would read 3685 - 8004. I've tried your method but i become more than confused!
just do 8004 -3685 and put a minus sign in front?
This helped me alot.. I'm in the process of going back to basics to do a maths test with no calculator which i always use at work.. i was just looking for simple maths tricks to make things easier. Great post.
Awesome!!!!
This is awesome... Is there an explanation as to WHY it works?
The "borrow" method is about getting 10's from another number what is the 1 up and 1 down method about.
Thank you!
give 10's then take it back in next column
The way I learned at school more than 50 years ago.... perfect !
You are awesome, thanks for sharing. I don't understand the new way of teaching my children their subtraction. I'm going to teach it to my 5th and 3rd grader. Thank you
+Roland Gonzalez Thanks
A Vulture Lord biker is a math teacher? Wow!
I learned to subtract using ur method...
great video, will the one up-one down method still work with subtracting decimals. thanks
this is the way I learned in school, now I'm trying to help my son and it's confusing (even though I understand) the way Americans do it.
This is the best method ever!!!!!!!! DUDE YOU ARE A GENIUS!!!!!!!!!!!!!!!
I think this is even better than sliced bread
I learned this way it’s easiest way to learn and you complete your work faster.
Whilst I totally agree that your - the traditional - method is far superior, I have one comment on your video.
On the top line you write a 1 in front of the 4 to make 14, however on the bottom line you write a 1 in front of the 8 to make 9 (not 18).
I think you should make it a bit clearer that the top line is raising the number by 10 but the bottom line is raising the number by 1.
For simplicity to help a learner I would suggest crossing out the 8 and writing 9 (or crossing out 9 and writing 10),
however for actual use - if anyone still does subtraction without a calculator - I would not write anything on the bottom line, because I only have to look at the top line to the right to see if I need to add 1 to my bottom number.
1 up 1 down is easier to remember and once you are taught it doesn't matter.
Thank you. I just tought my son this method. The other method was just too confusing
OANH PIETRZAK glad it helped!
Thank you! My 90 year old mother was taught this way, and even though she showed me once, I had forgotten how.
Ivant2B Alone Ahh. Glad it helped!
This is a great Method. Tought my 3rd grader in 5 min.
I am trying to find out an explaination why this works. Can anyone help me?
screencast-o-matic.com/watch/cFlifKryaJ Sure ... you simply are simply adding and then subtracting it back in next step. So I give 10 then take it back. 10-10=0. give 100 then subtract 100. give 1000 then subtract 1000 etc...
I learned this method 35 years ago ....in 2 grade. What is the mistery? I'm from Portugal and this is the method to teach everyone. Also, to do a long division, the european notation is more simple (Excuse my bad English!) ;)
This helps so much! And so much easier to do it this way! Thank you!
Glad it helped!
No, you can't model this with manipulatives. The decomposition method, where you trade a ten for 10 ones, and so on, is easy to show using materials.
This old fashioned "borrow and pay back model" works mathematically, but is incredibly hard to explain or demonstrate using materials to children.
Lorna. 7-7=0 1up1down then 13-4=9 then 1up1down 10-1=9 then 5-5=0 ANSWER 990
scrap that - i figured it out - i was reading the one of my figures as a 10 and not a 1!! Duh - it does work well doesn't it =D
Superb and easy, wish they'd teach this is my child's primary school, not sure what they are teaching the teachers to teach some the kids at her school. Over engineered maths
Sukiethenoodle absolutely, they over complicate things for them!
Totally! Teachers don’t think for themselves; just churn out what they’re told
Don’t you just love how TH-cam suggests little nuggets like this 9 years later 🤣
I'm a University level student, not in maths but, I felt like a failure not being able to do subtraction techniques. Its because they should have kept to this method instead of not making sure that students know this new one which is just confusing and messy. Gonna teach my brother this
Thank you.
Ahh thanks! Good luck with it. 👍🏼👍🏼
Thank you for sharing, it is good for kids.
Omg why has no one taught me this sooner!! Thank you for this
No worries ! So much easier than the stupid way they teach it now!
So a few years back I decided to resit my maths GCSE as part of my retraining as an electrician. The tutor tried to teach the new method but let me plod along with the old fashioned "one to the to and one to the bottom" method. I walked out 15 minutes before the test ended with an A**. The tutor, with a doctorate in mathematics, basically admitted afterwards that the new method is supposed to be idiot proof but anyone with half a brain should be using the old method.
Yes this is THE simplest way.
@@MrDarcy-OlMan the same went for division, multiplication and all the way up to the differential calculus I leaned for my advanced engineering diploma. Common core may make simple problems simple for simple people but, it soon becomes unwieldy in applied mathematics. God I feel like such a dick putting it like that.
Thanks for posting! This is the best ADHD friendly subtraction method! Mom taught me this when I couldn't do multi-step borrow/carry over method. Ive forgotten, how does it work woth negative number subtraction, such as 125 - 236?
J Pearson if the number on the top is larger than the one bellow then you do one up one down
I'm 19 years old I've been living on my own for a fucking year now and today completely forgot how to do subtraction because my brain is mush and this...definitely helped
Glad it helped bud 👍🏼
Both methods have their advantages and disadvantages. But this one is particularly hard to explain why it works. It also has the disadvantage of language "borrow and pay back" and "carry" that makes little sense. Lastly, "adding one to the bottom" makes that number look like a teen number, when you are meant to see it as "one more", unlike the ones next to a number on the top line.
Brilliant.
Ugh you're diversifying with this cheeky little video. I am a Geography lecturer and I've had to teach this method to many A level students who were taught other stupid ways of doing what is essentially easy arithmetic. I also had occasion to re-teach them how to do long division, multiplication, percentages and manipulation of fractions just so they could handle the maths involved in A level geography. Modern methods are woeful, trying to re-invent the wheel is a pointless exercise.
Thanks buddy. Yes well put. You’re exactly right.
thanks so much u made me and my daughters life easier hahaha
Kylie Michelle no problem!
THANK YOU SO MUCH
Wish they still taught this method at school! I've had to retrain myself to the regrouping of the top numbers 🤦🏻♀️
PEACE...This is OUTSTANDING TEACHING SIR!!!!!!!
Thank you 👍🏼👍🏼
very useful to public
Superb Sir,thnx a lot...
I know how to do that that is sooooo easy!! My dad teached me that already!
Excellent! 👍🏼
We just learnt this method by rote back in the sixties in the UK e.g.......4 take away 6 I cannot do, add a 1 to the top and a 1 to the bottom and so on and so on. As someone commented below all you have to think about is one column at a time no matter how big the numbers are you are working with.
Yes indeed. 👍🏼👍🏼
Awesome ! Thankyou!
Thanks buddy 👍🏼👍🏼
Yes, that's the way I was taught at school - really quick and simple. Now I'm having to help my 10 year old daughter with her maths but they are taught a really convolulted way of doing it now. I honestly can't figure out why they changed the method.
Indeed! They reckon the new method is easy to explain how it works, but if you don’t have a maths brain, it’s gobbledegook!
Really helpful so much better than compact column method
100% It's a case of the old way is the best way
Can someone explain to me rational or logic behind this method?
While the cross and write over is messy, the rationale is there, you borrow 10 from the next place value then only you can subtract accordingly (because now you have extra 10 more due to the borrowing)
Here I don't seem to understand.. when it is 0, you put 1 it becomes 10 ....but why when it is 8, you put 1 and becomes 1+8=9? Instead of 18? Why no consistency? How do you know whether it's actually just add 1 to the next place or +1?
When you put “1” up your giving an extra ten and the “1” down your giving an extra 10 in the preceding column.
We did a video explaining it if you can find it
At one time it troubled me that you are borrowing 1 on the top line, but paying back on the bottom line.
(In both cases from and to the column to the left)
How does this work?
The answer is that the top number is a positive number and the bottom number is a negative number.
To keep the entire sum balanced we have added 1 in the positive line (the top line)
so we also add 1 in the negative line (the bottom line)
The total value of the sum therefore does not change.
We did a video explaining how it works too!
This might be a stupid question, but it's been a long time since I've been in school, where do you get the take away from if you're not borrowing it from any other number?
So each time you can't do a subtraction eg 0-4 you just do a 1 up and 1 down everytime. Even with a 6 digit number?
Yes only do 1 up 1 down when you can’t. It can be any number of digits.
what is this method called?
Thanks
When I was a kid you borrowed a milk bottle and then put it back on the step. Exactly the same process, different words. Now what is your opinion on “chunking”? This is the modern method of making long-hand multiplication really difficult. I’ve forgotten the “modern” way of doing division but that was pretty gruesome as well.
All the modern ways are over complicated and a case of reinventing the wheel. Although I believe it’s for manipulating numbers mentally. OK for kids with maths brains but everyone else is bemused
@@MrDarcy-OlMan I agree. ‘Chunking’ fails on all counts. It has the same degree of complexity and has more steps making it more error prone. Another failing of modern education is a lack of focus on the ‘times tables’. Educationalists though try and argue otherwise. They say they are preparing children for the modern world. The product proves otherwise when young adults will use a calculator to work out what 14.036% of 100 is.
