My brain has decided it wants to do some quadratic equations. I have no idea why. If you know of a good website or app for refreshing math skills, I’d like to hear about it. #Math#Algebra#QuadraticEquations#AskFedi
@lydiaschoch I’ve been wanting to take an algebra course for ages. I miss it! Honestly, even DuoLingo Math is sort of scratching that itch. It’s elementary arithmetic, but I try to see how fast I can do it and it feels like a good brain exercise.
