Math Pro Free is a collection of calculators: Matrix Calculator, Complex Number Calculator, Factorial Calculator, Quadratic Equation Solver, Cubic Equation Solver, Exponent Calculator and Nth Root Calculator.
The Matrix Calculator supports square matrices with size of 2 through 10 and implements Determinant; Inverse; Transpose; A + B; A  B; A * B. The calculator has three (3) memories to facilitate argument manipulation for matrix calculations ([C] = [A][B] for example).
The Complex Number Calculator adds, subtracts, multiplies and divides two complex numbers. The result can be converted to Polar coordinates.
The Factorial Calculator allows you to calculate n! for any number.
The Quadratic Equation Solver finds the roots (real and imaginary) for a quadratic equation. Enter the coefficients for the equation and tap Calculate. EX. (5x^2  9x + 3 = 0).
The Cubic Equation Solver finds the roots (real and imaginary) for a cubic equation. Enter the coefficients for the equation and tap Calculate. EX. (4x^3  3x^2 + 3x + 12).
The Exponent Calculator finds the value of any number x raised to a power y. EX. (19^2).
The Radical Roots Calculator finds the Nth root of a number. Enter the number and the desired root. EX: (The 6th root of 64 (x = 64, n = 6), tap calculate and see the result (=2) in the answer box).
