AnalyticMath is a platform independent (Windows, Linux, etc.) mathematics program with a powerful editor and many integrated features that will allow you to expand and/or simplify algebraic expressions quickly and easily.
Calculator that performs the basic arithmetic operations on fractions and then at the press of a button gives you a detailed explanation of how the computation was done.
Calculator for vectors, matrices, complex numbers, coordinates, function plotting and intersections. Cartesian, spherical and cylindrical coordinates can be transformed into each other. Also integrated: editor, arithmetic trainer, calendar, and help file.
CalculatorX is an enhanced expression calculator. It supports Arithmetic, Logic, Bitwise and Relation operations. Constants and built-in functions can also be used in it.
Performs over a hundred simple, and complex calculations, with the ability to make several calculations simultaneously. Functions range from simple trigonometry, to Gaussian integrals, through 2D plots. [Win95/98/Me/NT/2000]
A configurable graphics calculator, which displays graphical representations of expressions and formulas, and lets you visualize parameter changes as video clips. Requires VB6 and MFC42 Runtime files. [Win95/98/Me/NT/2000]
