This is a very good app. Very little ads. Very cool. Much fun on my math homework.

Only turned out one mistake!

Seriously saved me when I was super late for class, simple and easy to use. Even lets tells you how to solve on your own~ only mistake was the it flipped the positive and negative of a specific factor so its always good to check your answers!

Need to be able to use large decimals/scientific notation

I like the set up and it is very simple, however you cannot put large decimals. I won't be able to use this app since a lot of the problems I need to solve are large decimals/scientific notations.
