    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.

      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

    • @JamilKhan-hk1wl

      You factorise the 10 first, 2*10*2*10 = (2*2)*(10*10). So do the 2*2 then multiply by 100

    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 find the answer 703 thinking a moment and then I went to see the video which also confirmed 703. What was frightening were all those lines and dots and the time they took to count them.
    Better thinking as 37x20 = 740, then subtracting 30 and another 7 = 703.

      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.

    but if you have a whiteboard and a marker/pencil, its not any different than just doing it the regular way

    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

    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.

      12
