Arithmetic tables --- Introduction ---

One may take it as an exercise or a game, but it is an important training tool for arithmetic operations. When trying to place the numbers into the table, you are forced to mentally compute their sums and products rapidly.

And with different configurations, the exercises may fit students from primary schools (positive or relative numbers, decimals) to senior high school or even more (roots, complex numbers, modular numbers). And the large size tables (3x5 or 4x4) may become very challenging.

Don't forget the case of products neighther, which helps you to understand the factorization.

Bon courage!
