  1. This is equivalent to the standard method we learn at primary school. To see why, use larger digits like 89 x 78 and notice that, instead of counting intersections, you'll be multiplying digits, carrying and adding the carry to the next column – just like you do in the standard method. The difference is the standard method is quicker. It is quicker to write the digit '9' than it is to draw nine lines.

  3. I prefer the basic method. ๐Ÿ˜‚๐Ÿ˜‚ This one's hard for me especially when I'm doing an oral one I can't image this one with big numbers.๐Ÿคฆ

  4. Great video, very visual and clear to understand. I attempted to use this method with higher digits (i.e 38 x 29) and got completely lost at where to separate the zones with so many lines all over the place ๐Ÿ˜‚

  5. Not useless my friend but actually very functional for those of us that see and interface with the world visually. Thanks for the video I loved it.
