jimthompson5910 (jim_thompson5910):

-7 + 3 is ???

OpenStudy (anonymous):

-4!

jimthompson5910 (jim_thompson5910):

and |-4| is???

OpenStudy (anonymous):

idk :/

jimthompson5910 (jim_thompson5910):

those are absolute value bars

jimthompson5910 (jim_thompson5910):

The absolute value of any negative number is just the positive version of that number ex: |-5| = 5 and |-12| = 12

OpenStudy (anonymous):

so it would be |-4|=4

jimthompson5910 (jim_thompson5910):

yes

jimthompson5910 (jim_thompson5910):

So -|-4| is ???

OpenStudy (anonymous):

4??

jimthompson5910 (jim_thompson5910):

well if |-4| is 4, then -|-4| is the opposite of that

OpenStudy (anonymous):

ummmm idk :/

jimthompson5910 (jim_thompson5910):

what is the opposite of 4?

OpenStudy (anonymous):

-4

jimthompson5910 (jim_thompson5910):

so if |-4| is 4, then -|-4| is the opposite of that...which is -4

jimthompson5910 (jim_thompson5910):

So -|-4| = -4

jimthompson5910 (jim_thompson5910):

which means -|-7 + 3| = -4

OpenStudy (anonymous):

so the answere is -4

jimthompson5910 (jim_thompson5910):

yes
