In this video, Mr. J explains how to subtract integers by adding the opposite. He provides four examples to illustrate the concept, showing how subtracting a negative number results in an increase in value, while subtracting a positive number decreases the value. The video emphasizes understanding the concept of 'adding the opposite' and offers additional resources for visualizing the process using number lines.
