Adding and Subtracting Integers

In this video, Mr. J reviews how to add and subtract integers, covering both positive and negative numbers. The tutorial explains two methods for adding integers: using absolute values and a mental math approach. It also covers adding integers with the same signs and subtracting integers by adding the opposite. The video concludes with a summary and links to additional resources for further learning.
