Adding Integers with Opposite Signs: Using an Algorithm

This video tutorial teaches how to add integers with opposite signs without using a number line. It begins with a review of absolute values and their role in addition. The tutorial explains how to add integers with the same signs and then moves on to adding integers with opposite signs using a number line. A common mistake is addressed, and an algorithm is introduced to add integers with opposite signs by comparing absolute values. The video concludes with examples of applying the algorithm to larger integers.

What is the absolute value of a number and how is it determined?

Explain the process of adding two numbers with the same sign.

What mistake do students often make when adding numbers with opposite signs?

How can you determine the sign of the answer when adding two integers with opposite signs?

Describe the algorithm used to add integers with opposite signs.
