Math Calculators.

Eight mathematics tools that show their working rather than just an answer. Algebra covers quadratic equations, the elimination method for simultaneous equations, diamond problems, and quaternion arithmetic including spherical linear interpolation. Arithmetic holds a square root calculator that prints each step of the simplification. Percentages covers reverse percentage problems, where you know the result and need the original figure. 3D Geometry calculates volume for cylinders, cones, spheres, pyramids and several other solids, and there is a degree to percentage converter for gradients. Each page states the formula, works an example through with real numbers, and sets out the cases where the standard method breaks down or gives a misleading result.
