Max explained the new arithmetic operator, haku, as the “crossing out of multiplication and addition. ” In this example, 2×5 = 10, so 10 haku 2 = 5. Max also proposes a symbol for haku, which looks like an equals sign with  up and down arrows attached to the end.

Although I’m just starting to understand haku and how it works, I think the implications for math are profound. I’m surprised someone didn’t discover it sooner.
