The program allows you to solve algebraic equations in the automatic mode. You just enter an equation in any form without any preparatory operations. Step by step Equation Wizard reduces it to a canonical form performing all necessary operations. After that it determines the order of the equation, which can be any - linear, square, cubic or, for instance, of the 7-th power. The program finds the roots of the equation - both real and imaginary.
