Playing with Pipo and the aliens the children learn and practise addition, subtraction and multiplication. Each level includes a system of prizes and rewards for completing the level. For beginner levels of addition and subtraction there is also a visual aid to help the child solve the problem.

*****************************************************
NOTE FOR PARENTS
In this version you can play with more than 40 levels.

Each one has a specific objective: add tens, subtract units, with carry-over, without carrying-over, the 12 times tables, etc. Choose those that suit your child's skills.

Currently it's available in Spanish and English, though, since the app is for mental math it is already practically international. It also includes new solving modes and configuration options so it can be adapted to different users.
