Formula Wizard is a simple utility that doesn`t even need installing and shows, in the same format as the Windows help, what you need to know about the syntax of all types of algebraic formulas.
Formula Wizard brings examples of transitive, commutative, associative and distributive laws, and also diverse examples of arithmetic and geometric formulas, complex numbers, matrices, proportions, cube equations, etc.
As Formula Wizard is shareware, it is limited. The complete pay version has examples of trigonomics, advanced calculus, differential equations, probabilities, statistics, etc.
