Customer Reviews


This app is incredibly helpful. Instead of making you pay an expensive fee it's about $1.99 per month and I appreciate that. It also really explains how you get your answer perfectly and there are different ways you can chose the method you use. You guys really deserve your five stars. In my opinion the payment was worth it.

I use it to help me check my son's homework

I use it to help me check my son's homework. I actually use it for other things too, but being that I've forgotten a LOT of my math skills this not only shows the answer but also shows you how you get the answer step by step if you want. Very well done.

Good tool for high school algebra and trigonometry!!!

I am constantly being stumped by my math classes, but Math 42 is extremely helpful for me.

I just wish that the developers would add a graphing calculator...
But overall I love it!
