This basic math game is ideal for learning and practicing mathematical operations of adding and subtracting. In a fun environment where children can learn to add and subtract progressively while having fun.

The game has a simple and pleasant graphical interface with different levels of difficulty, which will be unlocked as you overcome each level so that the learning is progressive, being able to repeat the times you want each level.

Each level gives the child 30 addition or subtraction operations, with which he can experience as many times as necessary until he succeeds in resolving addition or subtraction. To overcome each level, you must successfully solve 80% of the mathematical operations of that level, ie perform 24 of the 30 proposed operations of each of the addition or subtraction levels.

Let's have fun and to spend it well while learning.
