What you get is about 55 unlabeled equations on buttons that each call up a screen with one field for each variable. You enter all values except one, without a keyboard that allows exponents, and it calculates the empty field. The equations are at the high school level and are primarily Newtonian mechanics. Sorry no relativity, quantum mechanics, manifolds, graphs, text or even matrices. You can do all of this with a list of equations and the simplest calculator. It is more a test of if hype can sell someone’s first app that they have coded. I would recommend spending the cost on some notecards to use with a budget minimal scientific calculator. I give this a don’t bother recommendation. Sorry.
