A free program for Android, by NKdevelopment.
The objective of this game is to answer mathematical questions and perform basic arithmetic operations. The game has 3 difficulty levels (easy, medium, hard), so that kids can play easy games and more experienced players can play hard games.
This app is based on the concept of mental arithmetic, so kids need to use their mental math skills to perform calculations.
The math operations that you can perform are addition, subtraction, multiplication, division, and exponents (using positive or negative integer numbers).
Each operation can be performed in a few seconds, so you don't have to wait for your answer. Your answer will be displayed immediately after you've submitted the question.
