Help me so i can go eat lunch <3 ( question 2)

Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?

Explanation:

The notation 5(-2) is the same as saying "5 times negative 2"

The negative represents the amount of debt that Doug goes into when borrowing that $2. When borrowing the same amount over the course of 5 days, he'll be in debt a total of 10 dollars. So we'd write -10 to represent this.

You could also write it out the longer way

-2 + (-2) + (-2) + (-2) + (-2) = -10

There are five copies of "-2" being added up to arrive at -10

Though it's much simpler to say

5(-2) = -10
