# Math Tutorial 1.4 - Order of Operations and PEMDAS Rule

There are 8 lessons in this math tutorial covering Order of Operations and PEMDAS Rule. The tutorial starts with an introduction to Order of Operations and PEMDAS Rule and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific math lesson as required to build your math knowledge of Order of Operations and PEMDAS Rule. you can access all the lessons from this tutorial below.

In this Math tutorial, you will learn:

• What is the order of operations in arithmetic expressions that contain only additions and divisions?
• What are the order of operations in arithmetic expressions that contain only multiplications and divisions.
• What are the order of priority in expressions containing powers and the four basic operations?
• How do brackets affect the order of priority of arithmetic operations?
• What is the PEMDAS Rule?
• What is the order of priority in expressions containing various types of brackets?
• What is the sign of result in operations with negative numbers?
• How do you calculate the result of powers of negative numbers?

## Introduction

Arithmetic expressions usually contain more than one operation; yet most of them contain all five basic operations (including raising in power). Therefore, we must know where to start when solving them as not all operations have the same order of priority.

In this tutorial, we will explain how to find the value of mathematical expressions, from the shortest to the longest and most complicated. This guide therefore, will be a good base for future topics that include mathematical operations such as equations, inequalities, etc.
