After all that, I was expecting more than 86 lol

That's a new dance move right there

That one kid in the back (5th row) kinda looks like he's doing a "fake it til ya make it" lol. Even seems like he looks at his buddies answer first

My mom taught me math on an abacus, if I ever decide to have kids it's how they'll be learning as well. It's just a really good way to physically present math alternative to a purely mental construct. I honestly think schools should only allow an abacus or a slide rule until you hit college.

I honestly don't really know how people with purely western educations visualize math in their heads? It does kinda give you a bad habit of flicking imagery beads when you're doing mental equations, though that kid is especially spazy.

Chisanbop, kungfu math, or finger abacus if you want to read more.
