What is a in the equation?

The explanations are very good too, it solves simple and complex math equations and shows you how it did it. I've had issues with math, and this app has helped tremendously. It can literally solve any problems i had, i think this is the best math app I've ever used.

Simplicity is key, the best math assistant ever. Even the free version is fantastic. If you are a student you need to check this out. Could improve his maths with this app. It gives you the answers yes, but it also shows you step by step on how to actually do it, the software is just amazing and is out of this world.

It helps me with my homework and I really like using this app. It's giving me the confidence to be able to solve equations on my own. Keep up doing great stuff. It's beautiful app but unfortunately this app filter in Iran.
