Thank you for making things easier to understand.. I always had jitters with maths thanks to you I now can actually enjoy teaching math to my kids. We love you.

@@grandpasmurf2310 he wanted to learn a new way of multiplying numbers but there was no possible way he could've known it was what he already knew... Very simple really.
When I'm asked to times by 5, I usually times the number by 10, which is simply adding another zero to the number, and then divide that by 2. So if I times 50 by 5, I would add a zero to the 50, which is 500, and then divide the 500 into two, which is 250. It works with odd and even numbers too. Say I have to times 27 by 5, I would times it by ten, adding a zero, making 270, and then divide that by 2, which is 135.
Really good video! Helped me on my test at school and I finished first and got a great score! Thanks soooo much! BTW I subscribed to your awesome channel!
The easier of doing this and you're actually doing math is : 46*5 ----> 40*5 + 5*6 ----> 200 + 30 = 230 This process should take around 5 seconds at most. If you do this often, it will calculate it immediately
Here is more easy way to tackle it if we have 17x25 we can do it as 1x2 is 2 and 7x5 is 35, it looks like this (2_35)---eq1. Now we multiply and add 1x5 + 7x2 so it becomes 19 we can add this 19 in between our eq1 which is (2_35) so it becomes 3"93"5 and we add the two middle numbers which is written in between inverted commas.The Final answer is 425.
Yes, of course! 64x25 is the same as 16x100. 64/4 x 25*4! Very clever! 17x25 then is also easy, 17/4 is 4,25 and the 100 moves the comma two over so we have the 425. Only difficulty so far is how big the number is, if it's 3 or 4 digits. Why aren't these things taught at school? This is a great combination of both fun and educational, it's motivating and it can be useful in everyday life.
In fact, it can be calculated like this, for example, 125 times 32, how easy is it? Split 32 into 4 times 8 first, then this is 125 times 4 times 8 and then adjust the position of 8 and 4, it becomes 125 times 8 times 4, 125 and 8 times 1000, 1000 times 4 times 4 4000, so the answer is equal to 4000, and then a few knowledge points of science popularization are helpful to this form of simplicity, 25 times 4 = 100, 125 times 8 = 1000, 125 times 4 equals 500, 25 times 2 equals 50
Question, what would be 18 * 25, I know the answer would be 450 but still are we missing something? For example: Forgetting about the other numbers such as these? Like 22 ,23, 26, 27, 34, 35 and etc. Edit: I was making sure of something never mind I got it it would be explained like this right? So like this 22 * 25 = 22/4 = 5__ and then we would be adding two other numbers being 50 which would leave us with 550 right? Edit 2: Hopefully I didn’t write too much please don’t ignore the comment, maybe you were struggling as well hopefully my explanation wasn’t confusing. Edit 3 never mind I reviewed it a bit you did explain it, my bad (sorry for being a bit ignorant there).
And one other trick. If you don't like the numbers you are given to multiply, you can double the higher number and take half of the lower number, Or triple the higher number, take 1/3 of the lower one, or whatever such combo works 16 * 25 = 8 * 50 = 4 * 100 33* 90 = 11 * 270 = 99 * 30 = 2970
This is good and all but what about 63*25? Now you should do +1 instead of -1 because 62 doesn’t “go nicely” while /4 so you add one, get 64, then divide by 4, get 16, then multiply by 100, get 1600, and this time since you added 1 in the beginning, just subtract 25 from 1600 and you get your answer 1575 👍🏾 This is the other way you can do it if it doesn’t work
It is so easy to follow your logic. I wish you were there when I was at school. Shame I am retired now. Thanks for teaching me new things at my old age.
+Plumberman Jones THAT is exactly what he said in explaining multiplication by 5. What I hate and have always hated as a mathematics educator is that he is calling these "tricks." These are not tricks. These are mental mathematics strategies which center around understanding number sense. In the United States, we do not do a very good job of teaching number sense. We don't give kids time to explain their thinking and the bigger issue is that we don't take the time to learn number sense.
A faster, less complicated way of mental math multiplying 72 X 125 would be: 1) multiplying 72 X 100 = 7,200 2) Take one-fourth of 7,200 = 1,800 3) Add them both together: 7,200 = 1,800 = 9,000. It took me only 3 or 4 seconds.
I realy want to thank u so much for ur easy tricks. Keep on and never stop. we will always need ur support for our sons and daughters as well as ourselves.
@@taran9526 I wholeheartedly apologize for my inaccuracies, I don't understand why I would comment something that stupid. However, it seems you have misspelled grammar. Anyways koodos 😪
how refreshing, when I was a kid I was sooo good with math, being the youngest at home, I had to teach math tricks to my older sister she's 2 years older than I. Thank you so much I enjoyed your video.
I messed this up slightly Say you have 25 x 65 Step 1) Drop the 5's on each multiple So you have 2 and 6 Step 2) add 1 to the higher of 2 and 6... Now you have 2 and 7 Step 3) 2*7=14 Step 4) back to the original 2 and 6. Take 6-2 = 4 (the difference). If it's even number the last 2 digits are 25, if it's odd the last 2 digits are 75 Step 5) Take half of that 4 = 2. Round that 2 down to nearest integer. That's still 2. Step 6) the step 3 + step 5 14+2=16 1625
For 125 can't we divide it by 4 and multiplying it by 5000 and instead of multiplying it by that we can divide it by 2 and multiply it by 1000? Same thing cause 4*2 is 8 but maybe simpler?
For 5 I have always done the opposite. I multiply by 10 and then halve the answer. For 25 I simply do the method I use for 5 twice in a row. It seems it is the same method you show which is to manipulate the number 5 into the number 10 (or 100). I enjoy your videos very much, thank you.
Slightly better method is to first multiply by ten *then* divide by two (35*5 = 35*10/2 = 350/2 = 175) = (35*5 = 35/2*10 = 17.5*10 => you don't have to look for the smaller number but hey for the sake of simplicity => 17*10+5 = 175)
10 / 2 = 5 100 / 4 = 25 1000 / 8 = 125 10000 / 16 = 625 100000 / 32 = 3125 1000000 / 64 = 15625 10000000 / 128 = 78125 See the pattern? First number starting with 10 increase by 1 zero, and second number starting with 2 multiply by 2! This may help you multiply with bigger numbers.

There's always two ways in math. This is good too
That's basically what he did, but he just divided first instead...
Wow this is really great! I'll have to watch it a lot more to remember it but really nice trick, thanks.

could you plz do some integer videos i need to learn for a test next week!
very inspire! Thanks for this great video!!
Does that applies for other numbers?
Example: 16 = 32/2, so:
8x16 = 8/2x32, and 9x16 = (9-1)x16+16 = 8/2x32+16?
This is so helpful! Thank you
very genius trick thank you
thx u really help me in my maths thank u so much and for helping me at school too. also so for the people who didn't like this ur so mean

I already knew what u we're going to do because I just watched ur divide be 5, 25, and 125 video! It's just opposite😁
so if i follow this can be continue ig anyhting multiplied by 250 you would then devide the mulitplying number by 16 ? and so on ?
Yes, of course! 64x25 is the same as 16x100. 64/4 x 25*4! Very clever!
17x25 then is also easy, 17/4 is 4,25 and the 100 moves the comma two over so we have the 425. Only difficulty so far is how big the number is, if it's 3 or 4 digits.

You can just divide 60 by 4, you will have 15 then add 3 of 25= 75 at the end. You will be having 1575
Both ways work out. It's just 64 is closer to 63
Thank you so much 🙏🙏

what white board do you work on
I messed this up slightly
Say you have 25 x 65
Step 1)
Drop the 5's on each multiple
So you have 2 and 6
Step 2) add 1 to the higher of 2 and 6... Now you have 2 and 7
Step 3) 2*7=14
Step 4) back to the original 2 and 6. Take 6-2 = 4 (the difference). If it's even number the last 2 digits are 25, if it's odd the last 2 digits are 75
Step 5) Take half of that 4 = 2. Round that 2 down to nearest integer. That's still 2.
Step 6) the step 3 + step 5
14+2=16
1625
ESponge2000 25 x 65
2 x 6 = 12
2 + 6 = 8 / 2 = 4
12 + 4 = 16
16 x 100 = 1,600
1,600 + 25 = 1,625
For 125 can't we divide it by 4 and multiplying it by 5000 and instead of multiplying it by that we can divide it by 2 and multiply it by 1000?
Same thing cause 4*2 is 8 but maybe simpler?

Multiply by ten, divide by two

pleeease can u explain step by step, the parts where i have to use 8 to divide and all
10 / 2 = 5
