Let's refresh our memories about how regular multiplication works.
When you mulitply 2 positive integers (let's say a and b), you are combining b groups of a. For example:
You have 4 groups of 3, and you are adding them together to get 12.
We will do the same thing with negative integers.
So, the solution is
