Booklet: Getting Started with Mathematica 1.1.1 Getting Started with Mathematica A booklet entitled 'Getting Started with Mathematica' , published by Wolfram Research, accompanies every copy of Mathematica In this Chapter, we start by showing you how to perform basic calculations, learn the basic syntax of Mathematica and some basic commands using this booklet and the Help in Mathematica Start by using...
