Chapter 1 – Introduction

Chapter 1 introduces Wolfram Mathematica as a powerful computational software used for advanced mathematical computing, data analysis, and problem solving across education, research, and industry. It explains what Mathematica is, how users get started with the system, and how the notebook interface serves as the main working environment for input, output, and interactive computation. The chapter further guides the reader through the structure of notebooks, including cells, evaluation of commands, editing and creation of content, and saving files. It also introduces key working conventions such as arithmetic operations, Greek letters, and common shorthand commands used in Mathematica. Finally, the chapter builds toward practical use by explaining how to define variables and functions, clear definitions, combine operations, and access built-in documentation and function information to support learning and computation.
