I’ve taken both, though more algebra. And I haven’t seen you in ages Void, Hru?

I’m doing fine! How are you?

Yeah that’s true for almost everything. You need a strong grasp of arithmetic for algebra, you need a strong grasp of algebra for calculus, and so on.

I made something very mathy and thought it might belong here:

A “Numberphile” video on YT inspired this; look up “The Golden Ratio (why it is so irrational)” for what is going on.

How could I make the app Uzu, an interactive light show in HS? Sorry if this doesn’t belong here, I just know it needs a LOT of math

Well, a fraction is like an equation of division but with no actual solving.

I think some interactive particle motion things are possible; they won’t be as fast/smooth as in that app. The bigger problem is that Hopscotch currently has no way of detecting multi-touch. Or rather- the editor window in the app does know about two-finger pinch gestures to change object size, but afaik there’s no HS rule for responding to two-fingers, let alone 3 or more, right?
Do you have a sense of what math you think is needed, or, the gap between the math you know and the math you need? I bet something uzu-inspired is possible, and I’m happy to help brainstorm about the math. I know some math.

when you do division, some of the numbers don’t divide perfectly. Modulo make an output of the rest of a division (sorry it’s definitely not understandable). Here’s some examples:

0/4=0
1/4=1
2/4=2
3/4=3
4/4=0
5/4=1

you can see that it’s a increasing list. It’s very useful if you want to make a variable increasing in a loop.

hmm i re-read my post and it’s not clear. Can someone help me explaining pls? My english is bad
edit: oh nvm Sophia wrote something
