I need help understanding what it is that I need to accomplish with this? And how?

For this exercise, you need to implement the subtract, multiply, and divide functions. All of those functions return 100 in the starter code, so you need to change all of the functions so that they return the difference, product, and quotient of the two parameters.

Hint: All of the functions should look like the add function, but with a different math operator.

Hope this helps!
