MATHEMATICA

Mathematica is computer software from Wolfram Research, Inc. Mathematica provides an environment for manipulating mathematical ideas symbolically. For example, you can ask Mathematica to factor[X2−Y2]and Mathematica will return: (X−Y)(X+Y). You can as easily deal with the equation for a line in algebra as take the derivative of a function in calculus, or solve an elaborate mathematical model in engineering or economics. Mathematica, then, allows you to use the language of mathematics with about the same terms as in a textbook and about the same ease as doing arithmetic on a calculator.
