Latttice multiplication is much better for large numbers and deals with a lot of the carrying of overflowing digits which occurs in both normal and "Japanese" multiplication.

- boredguy8 14y agoyes, there are no '57 * 86' examples, which would be counting intersections for quite some time.
- DrDreams 14y agoYou guys are exactly right. This method is bullshit snake oil for weeaboos as it involves counting up to the product of every single product, which is tedious and error-prone. It is safe to label anyone who praises this method as a math-hipster or pretender who only likes the warm fuzzy feelings of simulated simplicity rather than actual, real, pragmatic, useful value. They should be fucked gently with a chainsaw.
