You can actually just divide the percentage by hundred and multiply with the given number for eg.
8% of 60= 8/100×60 = 4.8
so good
I'm in my 50s and wish I had been taught this way. Very clear explanations, thanks.
now 55 yay c:
You are not alone. I am in my 30s and still single. So ladies if you are looking for a sexy guy. Then there are some available out there. 🤭🤭🤭🤫
DesiredJessi that said they are in their 50s they can be any age from 50-59 lol

DesiredJessi ok lol
Randomly came across this video and thought, "Why not?" Turned out that I actually learned something lol. This really helps! Thank you so much!
This video is from 2013 and your still saving lives! I've passed months trying to understand stupid percentages and I could now say marvelous percentages! Thank you so much for sharing your knowledge!!!
I just spent the last hour doing math - for fun! Unbelievable. You are the best teacher I’ve come across in 43 years! I don’t think I will ever say I hate math again! It’s midnight and I don’t want to stop doing math problems.
I see people here getting their lives saved by this video while I'm sitting here past midnight learning math for fun. What has my life come to?

Where were you in '95 when I needed you most? lGreat job - you've achieved in 11 minutes what my math teacher failed to accomplish in 12 years. Kudos sir
For real, he is doing fantastic stuff. Deep down I always believed this was possible - for things to be explained better.

He said hes not wearing a cape.
I love Spiderman!!!
What about the ones that do wear capes...🤔
Your voice and method of teaching thrills me... as an adult, I never thought this was teachable to me anymore... 🙌🏽
Thank you!!! I truly mean it.
Throw it at the fan!
Nowadays you have the facility in youtube to pin your/a comment to the top
Yeah best teacher ever
Best teacher helped me pass my exams wish he taught other subjects too
You have helped me out so much. I'm in 5th grade, and after I finished watching, it was clearly locked in my brain. Great explanations.
:0 so youre now in 11th, amazing
u goin into college now ( ๐_๐)
Time flies, this kid is in college now.
Damn
Oh same I’m in grade 5
Thanks so so much dude its been like a few minutes and i know more than a week studying maths in school Why does school even exist TH-cam HAS IT ALL
But would you be looking this up if it weren’t for school?
@@MAVENdeNYC problem is school should be the reason you don't have to look this up.
honestly I learn more from youtube then school! "look it up on youtube"-teacher
Omg lol youre so right screw school love you tube
MAVEN true
You've broken down my fear of math. The anxiety of math made me avoid it like the plague. Now I'm actually enjoying math! Just wow. Thank you so much for this!
#educarepoint
Your voice is so hypnotic... Excellent way of explanation. When I was a kid if you would have been my teacher I would be doing much better in my life..:(
For me it's distracting and quite nasally. Accents make the distraction worse.
@@Flielow His Australian His Accent shouldn’t Matter his message is Great 😊
@@Flielow everyone in the world speaks with an accent. You have an accent
it took this guy less than 10 minutes to teach me something I didn't learn properly at school or the years after.
Thank you.
I'm so glad that my teacher had shown this to me last year. I check out allot of your videos when I'm having trouble in my Algebra 1 class.
Wow. I'm 26 and never learned this. Thanks so much this is so helpful!
who else hasn't started learning percentage in school and just wants to learn this for fun :) ?
me
Lol me
Meh
It's so cool that you decided to help people who need help in math over youtube. you helped alot
Just multiply it without changing the percentage and then remove the percentage
12% x 80= 960% = 9.6
51% x 70 = 3570% = 35.7
98% x 680 = 66640 = 666.4
21% x 60= 1260% = 12.6
jigmi lama how to solve percentages MENTALLY. Did you really multiplied 98 by 680 MENTALLY?
Uea its easy are you like a 3rd grader(sorry for bad english im from denmark)
Morris Andersen Or your just some 5 year old.
jigmi lama I think i just got tricked into doing it the hard way this time.
.
Thankyou SO MUCH!!! - I am revising for my entrance exam into Teacher Training.
Your videos are so relaxed and confidently presented.
Perfect for a Flipped curriculum
I love you man. I started watching all your videos on how to do math in my head and I can easily solve problems faster than a calculator 👌 I truly recommend this guy for you guys this genius way to do math is one of many that helped me overcome my fear for math now I love it
your a hero lots of teachers tried to explain this to me and i never got it except when i came here your the bestttt
I wish you had been my Math Teacher in high school!!
ty my guy this video is freaking 5 years old but it still helped me
What a great teacher!
65 years later, your formula is retained and easily attainable. Thankyou, bless you.🙏💖
Wow I like this way.. It's great for people who don't understand or have a difficult time.
THANK YOU SO MUCH MAY GOD BLESS YOU. I love math now.
Exactly
brilliant video!! this helps me majorly, and i'm barely seeing this 3 years after it was posted!!
31 years old. Never got the hang of percentages. This. Literal lightbulb moment. Thankyou!
Why couldn’t I get him as my teacher 🥺🥺🥺🥺 I literally watch a few of his videos and learnt more than I ever did throughout my years of being at school bearing in mind I’m going university next year
I'm tempted to just drop out of school and base my learning on you! Omg such a great teacher, thank you!
don't do it!!!!!!!111
Your videos are life changing! I've struggled with this sort of stuff forever but now I can finally do it! Thank you!
I have an aptitude test tomorrow and you have just made things much much simpler, thanks a million
I can't thank you enough for this! Never had a teacher who could explain percentages to me, always had to rely on calculators. But now it's so simple! It's surprisingly fun to do math, when you know what you're supposed to be doing!
Can't believe how easy this makes it.
love percentages now. thanks to you and only you. thank you
If I ran an airline I’d have tecmath as one of the inflight tv channels.
Then run an airline you should!
Sleep well!
Again, this really helped me. I have tried so many different methods with percentages and your teaching method has really worked with me. Thanks so much for sharing!
my whole life was a lie :L Thank You So Much for the lesson :D
Excellent, thank you!!
Wish TH-cam channels like this was around when I was in secondary school! You’re a great teacher
Thank you! I have a test tomorrow and had no idea of percentages but now I do, thank you!
Im in 2019 and wtf u made math simple thank u so much got my asvab tomorrow
you are a great teacher
It's grade 12 and I'm reviewing all these basic concepts like log decision and multiplication but now everything is a freaking logoriyhem and IM FREAKIG OUT.
Thank you for you calming voice, it is an oasis in a desert of pain.
I couldnt find any single video which uses your methods.....I love them..thank you so much!!!!!
You"re an excellent teacher, but sometimes I can"t hear you.

I had all volume settings at maximum on my computer, but my hearing is also poor in my right ear. I could just about hear it with the left headphone pushed hard against my ear. The solution is not necessarily to speak louder, but to increase the volume in the editing program. Always run a video first before posting to YT, so any such shortcomings can be corrected. An ad played at the end of this video and was so loud it almost burst my eardrum. That is one of the problems caused by posting a video with the sound level too low.
Take that earwax out of your ear and unclog your ear. I think if you stopped using your headphones so much, you may not go deaf overboard. 🤗🤗🤭
His voice made me think I had to pop my ears
Then turn ya hearing aids up
Thank you so much, this has helped me a lot.
Half a year of math and I could of watched 11 minutes of this! Great help
Kids have it so easy to learn outside of school now thanks to youtube and people like you. amazing work.
I just have to say, you explain this all in a really coherent and helpful way, for the last few weeks I've been utterly terrified about even beginning to tackle the numerical reasoning section of my UKCAT exam, but this is really informative and helpful, it's sort of helped deconstruct the mental barrier of "shit I can't do this at all" to "oh shit, I actually can do this!" thanks a lot man, I owe you one.
oh my jesus Christ thank you so much u saved my life with this video. good man
Thank you so much! I've been trying to study for my maths test that is coming up and I just couldn't grasp the concept the way that my teacher had taught me, so I decided to do a quick search on youtube and this has been a lifesaver. Thank you so much man!
Omg you are the best teacher I’ve ever had the pleasure of listening to. My grandson and I have mastered this today, cause I’d totally forgotten how to do it.
Your videos are amazing. Thank you so much
your are an amazing teacher but the problem is that i have to repeat several times to understand what you are saying.please try to make your voice a bit louder so we all can hear or just use the microphone thats better
Sample: 87% of 300 = 261
"Remember" - Percentage is always have dot to the left side ".87" if you going to multiply it. so multiply ".87" to "300" to get the right answer.
300
* .87
-------------
= 26100 . move the dot "." from right to left twice.
= 261
France Mantua Thank you so much for making this comment. I had SO much trouble with percents like this and then I saw your comment, tried it out my self and got the problem correct! Now I got A on my test, thank you dude.
+France THANKS SO MUCH
France Mantua thank you may god bless you
France Mantua Yeah I think that is the method they teach you in school etc. This video is a great way if you need to do it in your head and quickly without a calculator though.
This is a great method. Thanks alot!
But please next time talk louder we cant hear you very good even with the volume all the way up.
Really like the way your teaching method works and I think if kids and adults learn more from you in a 11 minute video than at school it shows that some teachers need to adapt teaching practices as everybody's
learning style is different.
Calm Aussie accent and common sense, both helped give me an extra tool to working out percentages . It helps keeps one in touch with the original math logic so often lost with calculators. THANK YOU ALL THE WAY FROM DUBAI. Bet you didn't expect fans this far out eh ?!
Teachers are undervalued, underpaid and overworked....put them all into government and we'll see how much change comes about.
For a future reference you should be one of those yoga teachers with your calm soothing voice LIKE the comment if u think so TOO!!!!
ikr
Thank you my friend. I am an Engineering Technologists for DOH, I love math...that being said I love it even more even in my spare time. Thank you again.
I wasn't taught these short cuts in school, but I guess that we were taught the basics well enough that I did it on my own, as did my brother, my husband and most of his family. I guess that only happens when you really enjoy math and like to play with it. Your method of instruction is perfect, explaining what we instinctively did very, very well.
You can just do 80 ÷ 100 to work out 1% and then × it by how much percentage there is. E.G 0.8 × 12 = 9.6
Your example is better thanks
I didnt get anything iam still confused
I sometimes watch this mans videos on an evening while drinking a beer. I was remedial class for Maths never sunk in at all. This guy gets me flying through them in less than 10 minutes. I need this sort of stuff under my belt because my son getting at that age were he needs the help with homework of this nature, and without this I would be of no help. What can i say its brilliant tutorial thank you again.
Now why didnt i see this video during my school days..!!! Im now the king of % calculations..!!! Thank you sir..!!
OR; "56% of 440" [1% is 4.40] [4.40 x 56% = 246.4]
(42%) [42% x 0.42 = 18.9]
etc...(1% of the givin # times the % amount )
for those who didn't learn it back in 5th grade.. Duh lol, jk ;) gl
(comment or like if your studying for the military! (*:
Sam Hillfoughr yeah, that's exactly my point too... ;)
also, why not just multiply the 1% by whatever it is you need to figure out? .6 x 21 = 12.6
You can absolutely do that he just want to have a slow pacing so you can understand
+noma hhh That's smart, thanks for telling me that:D
Andy Lin when I tried this method I completely failed, what could have gone wrong? The problem I failed on was 98% of 680 and I got 364.4
well, the way I attack it is 100% - 2*1%
100% = 680
-2*1% = - 13.6
680 - 13.6 = 666.4
9.8×68=666.4
YOU ARE AMAZING!!!!
for years ive been strugling with these precentage problems but now i can do it in a BREEZE thanks to you!!!
Thank you so much I used to struggle on this so much but now I'm so confident with it this really helped me out!
11.09....isnt 10%of 220=22, and half of that is 5%????
Yes...but in the video he's doing 10% of 440=44 and half that is 5% which equals 22.
So what half of 10 percent is 11 or divide by 10 in 50 per ent
nice but can't hear it well
This is seriously the best thing ever! I have always been terrible at math and have been struggling to help my daughter and then I found this! I could cry because I can actually understand this!!!!! Thank you!!!!!
thanks from Malaysia!! great method and works fab! ur a great explainer too!
couldn't you just do 12% X 80 = 960 then move the decimal place so it becomes 9.6???
Yes you can do it that way
PS. 12% X 80 =/= 960, 12 X 80 =960, if you put 12% X 80 = 960/100. 12% = 12/100.
It bug me seeing 12% X 80 = 960
Yes much easier for me
You are speaking loud enough
I loveee this teacher ,this teacher is fast and I understand more
You're like the Bob Ross of math. Why couldn't my teachers be this easy thirty years ago?
Great teacher, one complaint: I don't like how you write decimals
bruh.. ;-;
I know right, rip to those people with OCD ;p
talk louder please,i cant hear what you are trying to say my speaker and or my headphones cant pick youf voice up please speak louder
me too i think its bcs of his deep voice
That was really helpful and you have such a good voice to walk us through it as well. Thanks for this refresher!!!
You've helped me out so much you have no idea. I just couldn't get it ... until now... You are a blessing thank you so much x
i am really stupid and this is not helping me at all
Don't give up!
Yes u are stupid
Just multiply both numbers and move the decimal in the answer 2 spaces to the left
Ex: 51% of 70
51x70=3570
So the answer would be 35.7
Just always remember to take the zero off at the end of the number
Tuna Sub don't say that nobody is stupid
Tuna Sub hahaha look in the mirror😑
Thank you very much. You have no idea how much I appreciate your videos.
I'm taking the ACT in December and you helped me SO MUCH!!! THANK YOU!!!
LOVE this. It’s exactly the refresher that I needed. Fantastic job.
Schools should teach people percantages like this.
You've uncovered a great mystery.
Thank you so much. God bless you.
You have no idea how much this helped me... You're such a great teacher.. Thank you so much, subscribed for sure!
45 years old- revisiting maths from school (70’s & 80’s) learned more in a 10 minute video than years of maths in the state school system-UK states school suck-having to do the same with gramma,
Really great to discover I actually like maths 🇬🇧 thanks for the video 👍🏻
This was so helpful. Thankyou so muchhh
thank you so much I have been trying to fig this out for days and other videos nothing work I watched this and I got it!!!!
wow!! 10 minutes for such a valuable skill! love it. and using it on my case study interviews this weekend hopefully too
Thank you. What a simple but enlightening solution to a problem.
I've always struggled in this and I've gotta say this is the most helpful video for this topic.
After 4 years of constant confusion...I finally understand this! Thank you so much!
thank you for these, they are a great help
Your videos are really helpful to me as I study for my Praxis Core Exam. Thanks!!
