Partial equation
--- Introduction ---

This is an essential training tool for arithmetic operations.
It makes you to fill-in an algebraic equation, either with missing
terms or missingh operators, in order to make the equation correct.
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).
