Question

Evaluate |-10| - |-8| -2 2 18

Answer 1

`|a|=\left\{\begin{array}{ccc}a&for\ a\geq0\\-a&for\ a \ \textless \ 0\end{array}\right`

Examples:
|2| = 2 because 2 ≥ 0
|0| = 0 because 0 ≥ 0
|-4| = -(-4) = 4 because -4 < 0
|-10| = 10 because -10 < 0

Your question:

|-10| - |-8| - 2 = 10 - 8 - 2 = 0

Answer 2

2

Explanation:

Calculate absolute values

subtract numbers (10-8)

and... you get 2! :)

I know it is late for you, but I figure someone else would like to know the right answer.
