Addition and Subtraction

This application is ideal for your children to practice sums and straight lines with and without the same as in school, performing calculations of operations number by number, with various levels of difficulty.
It also has the possibility of making timed accounts, where you will have several levels of difficulty, being able to move to the next level, which will have less time, but having to overcome previous levels. This application is ideal for children in primary and elementary education to have fun playing and practicing mathematics.
Do not miss the Multiplications and Divisions application that will be available shortly.
