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.
