# Introduction and Index

Unified English Braille (UEB) is a complete code. It is a code that is used for both literary (non-technical) and STEM (technical) materials. This tutorial is designed to teach UEB for technical materials with a focus on mathematics. The content is organized in chapters, with lessons accompanied by exercises for writing, reading, and proofreading. The lessons begin at a very basic level with numbers and simple operations, and gradually increase to more complex mathematical functions.
