What do u think ur answer is @ttop0816?
OpenStudy (ttop0816):
23?
OpenStudy (mathstudent55):
First take each absolute value.
Then use the order of operations.
OpenStudy (comm.dan):
Then, what is ur answer? @ttop0816
OpenStudy (mathstudent55):
Correct.

No.
The -8 remains as -8. it has not absolute value sign.
-8 * 2 = -16
OpenStudy (comm.dan):
That is what I meant to say @mathstudent55
OpenStudy (comm.dan):
Anymore questions? @ttop0816
OpenStudy (ttop0816):
ohhh
OpenStudy (ttop0816):
then for this question
Evaluate |5 - 15|.
it would be |13| right?

because they had the negative inside of the absolute value?
OpenStudy (comm.dan):
No.
OpenStudy (ttop0816):
oh sorry i meant 10!
OpenStudy (comm.dan):
Yes
OpenStudy (comm.dan):
I think what is 15-5 and then what is the opposite of that number

|5 - 15| = |-10| = 10
OpenStudy (comm.dan):
That is what I do, too. @mathstudent55
OpenStudy (ttop0816):
then what about this one?
Evaluate 3|-3|.
would that still be -9?
OpenStudy (comm.dan):
No
OpenStudy (comm.dan):
Think what is the opposite of -3 and think of that every time u have a negative number in absolute value terms

OpenStudy (ttop0816):
so it would be just 9?

|dw:1378013873083:dw| @ttop0816
OpenStudy (comm.dan):
Yes

OpenStudy (mathstudent55):
First you need to take the absolute value of -3, then you multiply it by 3:
3|-3| = 3 * 3 = 9
