 NumBasis NumBasis is a basis tool converter for integer numbers written in any of the main numeration systems (decimal,binary,octal,hexadecimal).It supports large number formats(5digits hexa,7digits dec) and fast calculation   Quadratic equation solver free This free application solves a quadratic equation and returns the roots(even imaginary roots)   Graph2Go Graph2Go  Graphing calculators are instrumental in teaching and learning mathematics. It is an environment that supports conceptual understanding of functions in general, and school algebra and real analysis in particular. Especially, it enhances connections between graphic and symbolic representations   Solve2Go Solve2Go  supports solving equations and inequalities by means of conjectures based on visual thinking. Conjectures can be refuted or supported by examples provided by the tool, and should be proved using symbolic manipulations on paper.
Equations: when we want to know for which values of x the two functions are equal   Equation Solver Equation Solver is intended to solve systems of linear algebraic equations with real coefficients of the second and third order (with two and three unknown).
