MathMax will guide your child step by step through basic arithmetic operations. It will help your child to understand the procedure to do an addition, substraction, multiplication or division.
It is also ideal to practice operations or to correct those that the child did wrong, because MathMax will show him the exact place where his operation was wrong.
It has a very easy-to-use and intuitive interface. It works in 3 steps:
1) Just touch the icon of the operation you want to perform at the top of the screen.
2) Then use the calculator to write your operation. For instance, "2345 + 356" or "357 x 256". Then touch the "=" sign and you will get the result at the top, as with any usual calculator. But you will also be able to see the resolution of the operation step by step, at the right side, in the notebook-like side of the screen.
3) Just touch the buttons "next" and "previous" at the bottom of the notebook-like screen to navigate through the operation you're performing. MathMax will then show to the child every step of the sum, substraction, multiplication or division he (or she) performed.
