The Japanese Multiplication Strategy

This strategy for solving multiplication problems can be very helpful when solving problems with larger numbers without a calculator handy.

I shall use this knowledge to confuse my math teacher

This is fascinating. As someone who has ADD and struggled with math my entire life, I was able to learn this and perfect it from this one video because I’m a visual learner. You’re a great teacher, wish I would have had a math teacher like you back when I was in school ❤️

0:35 12×13
2:24 15×23
4:46 37×19
So nice trick
Thanks 🙂🙂

Hi! This is interesting. However, I think that you could improve the algorithm by combining simple one-digit multiplications that most children learn by heart. Even in Sweden, we do this. In the last example, instead of carefully count every 63 intersections in one "bubble", we write 7 x 9 = 63.

Ive been struggling in maths so any video on YouTube helps and the more I know then the better of i will turn out in the future thankyou for Posting this video

[atomicblastoise]

Great, now I know that I suck at math in two langauges...

[robbiewright]

I was today old when I learned this!! 55 years old. Amazing!!

[enlosluceros]

I never liked math but I love this method and I'm going to teach it to my children.

[jimclarke]

Excellent example, easy to understand.

[widdershinnz]

LIFECHANGING holy crap I’m able to math now!!!

[alexkpih_iykwim]

Quick question, how would I do it with a equation like 360*23 or something?

[chaksanu]

Mam its quite fascinating, infact your way of explaining its amazing ...Thank a ton for sharing this trick.

[myathehappy_]

wondering how to do zeros, like 20 X 20?

[priyarompicherla]

What if you had a 3 digit number, also are you gonna draw 9 lines if the number was like 99×99

[wanhedacoimhthithe]

Japanese math is with less lines in the math you are doing. This can be helpful in some cases but not proper way. Some Japanese math can be with more lines but carrying a number over and adding on to your smaller circles before adding it to your final answer.

I need more detail on counting the inner sections. I need you to slow down and zoom in on what your touching and counting please

[parthim]

Hi I'm from India Tamil Nadu I can understand this video thanks 😊 so much 😊

[siana]

I’m by blood Japanese here to give u support

[ronaldjorgensen]

do the jump to trigonometry solid squares show a square root once only or do some calculus can you show base 8 math or octal

[JustinK]

but if you have a whiteboard and a marker/pencil, its not any different than just doing it the regular way
the real trick is doing it in your head,
012
013

in your head -> 2x3=6, 2+3 = 5, 1x1 = 1
of course i started with the 1's column first, so just reverse, 156
