Mastering Integer Addition and Subtraction Techniques

This video tutorial explains how to add integers using a number line. It covers the addition of positive integers, mixed integers (positive and negative), and negative integers. The tutorial provides examples and explains the rules for integer addition, including the sum of two positive integers, two negative integers, and a positive and a negative integer. It also highlights the concept of moving right for addition and left for subtraction on the number line.

What is the first step in adding two integers using a number line?

• Find the larger integer on the number line

• Find the smaller integer on the number line

• Find the first integer on the number line

• Find zero on the number line
