# Arithmetic

### Welcome to the Arithmetic Handbook!

Arithmetic is a topic of math having to do with the manipulation of numbers. This book will teach you the ins and outs of arithmetic, including fractions, radicals, exponents, bases and more! Although it is recommended (and assumed considered you can read this text well) that you understand basic mathematics, you do not need to know any math to start reading this book! Just select the topmost page and start reading from there. There will be examples on the bottom of each page for helping you understand the concepts further. Enjoy!
