SUM Brains is a Maths App my daughter designed on paper and which I have created for her.
The app will help you master the basic Maths Operations addition, subtraction, multiplication*, and division*.
You can either choose to do some Training where you have 10 equations to solve or simply Play and solve the equations as fast as you can to avoid the time running out. Try to get the Highest Score on Game Center and become Number 1 in the World. Share your Highest Score and see if your family or friends can beat your Score.
