Integer Operations and Chip Models

This video tutorial explains the concept of using integer chips to understand the addition and subtraction of integers. It highlights that subtracting an integer is equivalent to adding its opposite. The tutorial provides examples using integer chips to demonstrate that subtracting a negative integer is the same as adding a positive integer, and vice versa. Through examples, it shows that negative 6 minus negative 2 equals negative 6 plus 2, and positive 6 minus negative 2 equals positive 6 plus 2, confirming the rule A minus negative B equals A plus B.

What does a positive chip represent in integer operations?

• Positive two

• Negative one

• Zero

• Positive one
