Integer Operations and Chip Models

This video tutorial explains how to use integer chips to understand the relationship between subtraction and addition of integers. It demonstrates that subtracting a positive integer is equivalent to adding a negative integer, and vice versa. The tutorial uses examples with integer chips to visually show these concepts, helping learners grasp the idea that subtraction can be viewed as adding the opposite.

What does a positive chip represent in integer operations?

• Negative one

• Zero

• Positive two

• Positive one
