Hello guys, I don't know where else to post this but here goes.(adsbygoogle = window.adsbygoogle || []).push({});

I'm going to be catching up on a looot of math this year. Unfortunately a lot of the math books that I'll be using only provide the answers to odd numbered questions. And the answers that they do provide a lot of the times "do not show the work". Is there software out there that will provide detailed proofs and solutions to most precalculus-calculus math problems?

Thanks.
