Often we need the output of first (previous) calculations in our next (coming) computation. For example write the following line for basic arithmetic in Mathematica Mathematica can perform basic operation of additions (+), subtraction (-), multiplication (*), division (/), exponentiation(^) etc. Each time you enter or change the input you will notice that the “In” and “Out” labels will also be changed.

The inner most brackets enclose the input and output while the outer bracket (larger bracket) groups the input and output together. You will also see set of brackets on the right side of input and output. Note that Mathematica places “In:=” and “out=” (without quotation marks) labels to 1+1 and 2 respectively. This is called evaluating or entering the expression. You will get answer on the next line of work area. Type 1+1 in notebook and press ENTER key from keyboard. Mathematica notebook with text, graphics, and Mathematica input and output Initially windows title is “untitled-1” which can be changed after saving the notebook by name as desired. Starting Mathematica will open a fresh window or a notebook, where we do all mathematical calculations and do some graphics. A tool for preparing input to other programs, or to process output from other programs.An interactive environment for exploration of numerical, symbolic and graphical calculations.

A language for developing transformation rules, so that general mathematical relationships can expressed.

A calculator for arithmetic, symbolic and algebraic calculations.

This introduction to Mathematica will help you to understand its use as mathematical and programming language with numerical, symbolic and graphical calculations. Mathematica is available for different operating systems, such as SGI, Sun, NeXT, Mac, DOS, and Windows. MATHEMATICA originally created by Steven Wolfram, a product of Wolfram Research, Inc.
