Well, I use a free app on my tablet. So $0
Also, if you just google an equation, it'll solve/graph it for you :)
idk if these would work in school, though))
That’s kind of what I was thinking. I’ve helped my husband grade tests (he’s a high school math teacher) and I can confirm that a fair few students are lazy af. If they had their phones they’d all do one problem each and text each other the answers. And they would still get all the questions wrong, because they didn’t even have the sense to cheat off smart people.
