FX Calculus Problem Solver

Pay without using means simply "stealing money"and that's exactly what you do. I got your premium version but simply don't work each time i type a equation. Complains going further if it's what you looking for !

Great…

Nice it was amazing

Assuredly, Thanks!

Best investment of my college career

This app has been excellent at helping me remember calculus concepts that I might forget. Obviously, there are a few flaws, but it’s pretty good overall.

I have had this app for a couple of years now and Appreciated it greatly until I tried to do a summation. This seems to be a serious flaw considering the manner in which calculus is taught. What is one to do, use an integral instead?

It’ll ask u for your Apple ID. Don’t put your password in. And u gotta pay for the content that is really important.

Paid $6 for full access as soon as I paid app stopped working. Scam. Save your money.

The recent update is much appreciated. This is one of the finest math-review tools I use. In an instant math concepts can be researched and I find my forgotten knowledge refreshed, well done.
