 These objects are one variable first degree equations of all sorts, plus the case of x² = a (which includes the calculus of a right triangle's side's length using pythagorean theorem). Later they might also be equations of higher degree.

+The main methods are solve_next_step(), which determines what is the next step in the solving of the Equation, and auto_resolution() which uses solve_next_step() to produce the entire resolution of the Equation.
