Definition: TeX stands for "text engine." It's a system used to create mathematical documents, including equations. TeX requires a special software called LaTeX to work with it. The main goal is to format text using commands that are automatically generated by the LaTeX compiler. This includes things like breaking up long strings of text into sections and using math operators such as addition, subtraction, multiplication, division, exponentiation, etc., all in a way that's easily understandable for humans.
