Question

Find the value of -|9| - |4| - 3|5 - 7|.

Answer 1

|x| means the distance of x from zero, so find the value of x (if you even need to calculate it) and make it positive. To do this problem I would start by calculating the last absolute value because that is the only one that needs to be calculated.

|5-7|=|2|=2

Then take all of your other values out of the absolute values (||) by making them postive

So you should have
-(9)-(4)-(3*2)

You leave the negatives that are outside of the || alone because they are not part of the absolute value

-9-4-6=-19
