# Understanding Arithmetic

by Ron Kurtus (updated 16 March 2023)

* Arithmetic* is a branch of mathematics dealing with the properties and manipulation of numbers. It includes the numeric system and counting, as well as the mathematical operations of addition, subtraction, multiplication and division.

Performing these operations with fractions and decimal fractions are also included. Oddities in numbers, numeric games and using the calculator are also considered part of Arithmetic.

I've found that understanding the fundamentals of Arithmetic is important in being able to do common mathematical tasks, as well as move on to Algebra and other math subjects.

The purpose of these lessons is to help you gain understanding the basics of Arithmetic, such that you do well in school and become a champion in the subject.
