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 ❤️
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 UA-cam helps and the more I know then the better of i will turn out in the future thankyou for Posting this video
With zeros , you can add a zero to the end so eg 23*20. Do 23*2=46 and add a zero on end so 23*20=460. I don't know if this is the proper way but it's how I would do it
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 don't understand why people need this. Never needed it in school and I have ADHD and I consider myself an average mind. I could calculate thiese things in my head in no time eversince we learned the big multiplication table.. which was in what? 3rd grade or whatever. I was maybe 6 or 7 years old. More like 7 or 8 actually. By the time you counted to 63 I had already calculated the multiplication in my head for the 3rd time and by the time I would finish counting 63 places I would have to count again because I probably miscounted.
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 x------ in your head -> 2x3=6, 2+3 = 5, 1x1 = 1 of course i started with the 1's column first, so just reverse, 156
Are the steps the same for single and triple digit numbers like 8x4 or 125x144 or is there different methods if so do you know where I can find a video explaining it?
It’s the same no matter how many digits. I just saw a similar video on Reddit a couple days ago. It’s easier especially if you are a visual learner or if you know your single digit multiplication. Very original alternative for multiplying.
Does it matter which angle you start your diagonal lines from left top corner to bottom right or upper right to bottom left and does the first digit on both numbers always go above the second digits lines would it matter
It is not clear that weather it's Chinese or japanese, this method also called line and stick method. Maybe for the reason to keep it simple they named as...
I, and probably all the Japanese don’t learn this method. Instead, for example, to calculate 12×31, a normal method is used(I’m not sure if it’s displayed correctly): 12 X 31 --- 1 2 3 6 --- 3 7 2
i am stuck in the walls of the ones place. the nightmare is coming. i am stuck in the walls of the ones place. do not talk to the one in the ones place
Somebody solve this number 99*99 this trick is very difficult to apply in large number ..this trick is only possible to fast in very small number like 22*22 and 12*31
I'm trying to figure out the limit. I think it's 4. So for example if there's a number with a 5 or higher in any of its places, you wouldn't use this method on it.
I shall use this knowledge to confuse my math teacher
Lol same
XD same
U guys are cruel

So nice trick
Thanks 🙂🙂

Could you please further explain? I don’t fully understand.
Oh now I get it lmao she counts out 60 intersections 😂
Like who tf does that
At that point it's really no different from long multiplication. It's just a visual representation of it
Ive been struggling in maths so any video on UA-cam helps and the more I know then the better of i will turn out in the future thankyou for Posting this video
I was today old when I learned this!! 55 years old. Amazing!!
37 years old here. This would’ve made elementary school easier and would’ve made multiplication fun
44 yrs, young rite here
LIFECHANGING holy crap I’m able to math now!!!
Excellent example, easy to understand.
Great, now I know that I suck at math in two langauges...
I never liked math but I love this method and I'm going to teach it to my children.
Woah this is actually pretty cool
Quick question, how would I do it with a equation like 360*23 or something?
Triple digits would require you to draw a third line through your intersections
@@t.j.carlson7913 But you don't count anything on the zero line or use a red line to not confuse yourself
Just do 36 × 23 and add the zero in the last simple
Mam its quite fascinating, infact your way of explaining its amazing ...Thank a ton for sharing this trick.
I shall now be smarter starting today
Hi I'm from India Tamil Nadu I can understand this video thanks 😊 so much 😊
Is there a need to mention your country??
I’m by blood Japanese here to give u support
Really? I wonder what Japanese blood looks like? Is it different to the rest of the human race?....just kidding happy new year 😍
@@SuperFootball78 that was kind of sus, japanese blood? Are you a Ghoul or something xD?
@@follower3793 good one lmao
wondering how to do zeros, like 20 X 20?
With zeros , you can add a zero to the end so eg 23*20. Do 23*2=46 and add a zero on end so 23*20=460. I don't know if this is the proper way but it's how I would do it
You factorise the 10 first, 2*10*2*10 = (2*2)*(10*10). So do the 2*2 then multiply by 100
@@breannamarshall1467 but what happens for example if the zero is in the middle, like 32*107 ?
Thank you!This is kinda very easy
great video. Thanks
Awesome lol thanks for this video. I couldn’t figure out how to use this solution with digits over 4
What if you had a 3 digit number, also are you gonna draw 9 lines if the number was like 99×99
Thanks
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.

This will be helpful for my maths at college
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
I love this! Though I'd need a MUCH bigger paper if the math was smth like
52,087 x 3827
Just saying 😂
This is great
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
x------
in your head -> 2x3=6, 2+3 = 5, 1x1 = 1
of course i started with the 1's column first, so just reverse, 156
Thank you so much
I liked a subbed tysm it worked and this is very educational thank u
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
As a japanese, I have never seen this wethod. However, its interesting.
thanks
Wow, I wish they taught this method in my school.
Me as Indonesian admit the best method for math is India (Hindi) method.
Are the steps the same for single and triple digit numbers like 8x4 or 125x144 or is there different methods if so do you know where I can find a video explaining it?

My time has come
Meet the Trickster
This knowledge will be used to confuse my teacher
Thank you for teaching me your ways all mighty one
Nice
You should of shown a variety of numbers, two digit and three digit multiplication maybe even 4 digit 😊
What is the number has a 0 in it?
How much line would denote 0?
You should be my teacher
Qt fun to learn a new method.
Jks aprt I thought u were drawing doll
You got simple answer in multiply
Does it matter which angle you start your diagonal lines from left top corner to bottom right or upper right to bottom left and does the first digit on both numbers always go above the second digits lines would it matter
The angle should be angled like they have it. I personally would start with ones spot
Why is it called the Japanese multiplication strategy?
Because japanese build their homes from sticks
It is not clear that weather it's Chinese or japanese, this method also called line and stick method. Maybe for the reason to keep it simple they named as...
I, and probably all the Japanese don’t learn this method. Instead, for example, to calculate 12×31, a normal method is used(I’m not sure if it’s displayed correctly):
12
X 31

3 7 2
Why did you make something so simple so complex
102×103= how can do use this method
Teach as 3 digital number to calculate
This is so cool
Wow that is neat

Somebody solve this number 99*99 this trick is very difficult to apply in large number ..this trick is only possible to fast in very small number like 22*22 and 12*31
this it is so hard i try this rule more than 10 times i do not find value 18 * 38 🤔🤔
Can you do 45 x 38 for me ?
345 the answer
15×23
i dont get ot
I kinda get it though
703 the answer
I feel like this is a cool trick but it’s honestly so inefficient. Maybe it’s a good means of visualizing the numbers but damn this could take a while
I'm trying to figure out the limit. I think it's 4. So for example if there's a number with a 5 or higher in any of its places, you wouldn't use this method on it.
SECOND GRADE SECOND GRADE!!!!!!
Wow so 37x99 would be alot of friggin counting
you should of started making caveman sounds and farting politely
so does it mean japanese people still uses this method? 🤨
WHY?!??! YOU MAKE ME GONE MAD!!!!!!!!!!
Hai
General Kenobi
How do I add *.5?
That would be changed into division by 2 so that wouldn't be a multiplication problem
12×13=156
4 digital number
This has a lot of logic…but drawing all those lines…damn! Imagine calculating 99999999 x 99999999 😂
19*91 😂
It’s interesting but so very inefficient.
Yeah, that's why they had to invent the calculator, they were running out of paper by the end of a school year
I've never used it :/
This takes away allll thinking lol
Why didn’t they teach me thos
Only I Japanese do not know where to calculate.
It doesn't work I did it
Tickling my ear
i cant
WHY
*it
uhh
Much easier. NOT. Still crazy amazing though.
Hahahahaha Japanese never do that😂 I'm japanese but I've never seen the people calculate like that lol
really?
99 x 99
Oke bye😋😋😂
5000*1000 do it with japanese method
lol
50000
Easy
And you could even make it a hard equation?
@@cartoonsandplaythroughs6898 check your math... i feel embarassed for you, sorry mate.
jajaj useless
It maybe nice but calculator is faster.
