Mastering Integer Addition Techniques

This video tutorial covers the concept of opposites and additive inverses in integers, explaining how they are the same distance from zero but on opposite sides. It demonstrates adding integers with the same and different signs using number lines and real-world examples. The tutorial includes practical exercises to reinforce understanding, such as finding the sum of temperatures and solving integer addition problems using the commutative property.
