With a title like "It is also used in schools and cram school", you might think that we are talking about a textbook. But this is not the case. We are talking about a math app for children. We have designed this app to make learning math fun.

As we have mentioned in the description, this app contains a full range of math problems that children can learn in the elementary school. You can choose to learn by yourself or with your child.

You can select the problem to be solved and the method to use.

We have a problem and unit section. The former contains all the problems and the latter contains all the units.
