The application acts as an Arithmetic calculator for expressions with all variables bounded or as an Algebra solver when formulas come with free variables. At any time free variables can be bounded and the expression(s) re-calculated. It is possible to define a list of expressions. Each expression is assigned the unique name, which can later be referenced in other expression(s).
