Understanding Integer Addition with Absolute Values

This video tutorial explains how to add integers using absolute values in three steps. First, find the absolute value of each addend. Next, check the signs of the addends: if they are the same, add the absolute values; if different, subtract them. Finally, determine the sign of the sum by using the sign of the addend with the higher absolute value. The tutorial includes examples to illustrate these steps and encourages students to review the material and ask questions if needed.

What is the first step in adding integers using absolute values?

• Determine the sign of the sum

• Check the signs of the addends

• Subtract the smaller absolute value from the larger one

• Find the absolute value of each addend
