If x = -24 and y = 6, what is the value of the expression: | x+y |

Replace x with -24. Replace y with 6. Then use PEMDAS to simplify

So we have x+y = -24+6 = -18

If the negatives throw you off, then think of it like this: you are 24 dollars in debt so that is represented by -24. If you pay $6 back, then you are 18 dollars in debt (24-6 = 18)

Or you can use a number line. Start at -24 on the number line. Then move 6 spots to the right to land on -18



Since we have vertical bars surrounding x+y, this means that the result will be positive. Remember that absolute value represents distance. Negative distance makes no sense. 

So |x+y| = |-18| = 18

Final Answer is 18
