ATN Problem 1.4 In the Chips

How can you use a chip model to represent addition and subtraction?

In this investigation, we will be using chips to represent positive and negative integers. 

You may have heard the terms, "In the red" (meaning you owe or have a negative amount of money) and "In the black"(meaning have a positive amount of money)

In the image above, there are black positive chips and red negative chips on the board. Some red and black chips have already been put together in "zero pairs" that cancel each other out. Is this image "in the black" or "In the red"? How do you know?
