Learn primary math for free is a free app based on the study of math that is aimed at children in kindergarten and primary school.
In this application they learn addition, subtraction, multiplication and division at different levels.
Each operation contains four levels of learning:
In the first one, children learn visually by adding and subtracting fruits and multiplication and division tables have been added.
The second level involves performing mental calculations of simple operations and is good for reviewing the first level in order to strengthen knowledge.
In the third level, simple operations are performed by typing them on the screen.
The fourth level introduces more complex operations which are solved by writing them on the screen, just like the third level.
