Subtracting Integers with a Chip Model

The video tutorial explains how to use a chip model to subtract integers, focusing on the concept of zero pairs. It provides examples such as -5 minus 1, 5 minus -2, -1 minus 2, and -1 minus -4, demonstrating how to manipulate the board to achieve the correct result. The tutorial emphasizes understanding zero pairs and maintaining the board's value while subtracting.

What is the first step when using a chip model to subtract integers?

• Add zero pairs to the board.

• Start with the second number on the board.

• Start with the first number on the board.

• Remove all chips from the board.
