The video explores the relationship between addition and subtraction, demonstrating how they are inverse operations. It begins with solving an addition problem, 4 + blank = 10, by adding numbers to reach a total. The video then explains subtraction as removing numbers from a total, using the example of 10 - 4. Patterns in addition and subtraction are identified, showing how one operation can undo the other. The concept of inverse operations is highlighted, emphasizing that addition and subtraction are opposite processes.
