Compare using < , > , or = –│2 – 5│ _____ (8 – 11)

OpenStudy (anonymous):

what confuses me is the -l 2-5 l what am i supposed to do with the - sign on the outside?

OpenStudy (anonymous):

The pipes | | mean absolute value, so if it's a negative, you turn it into a positive 2 - 5 = -3. then apply the absolute value to get 3. The negative sign at the front is basically -1 * (number here), so if the number is a negative, it'll turn positive if the number is positive it'll turn negative.

so it's grater than >

OpenStudy (anonymous):

= since -3 = -3. :)
