Order of operations if i am not mistaken you got PEMDAS add first then subtract then divide by 2
OpenStudy (anonymous):
So the answer would be 1? I thought for PEMDAS you Divide first, add, then subtract.
OpenStudy (notamathgenius):
You cant divide until you have an answer is 1 an answer? I got 7
OpenStudy (anonymous):
Yeah, 1 is one of the choices. 7 is not one of the choices.
OpenStudy (notamathgenius):
Ok I would go with your answer i must have dont it backwards, let me re do it

yea i got 1
OpenStudy (anonymous):
18 – 4 + 12=26
then 26/2=13
OpenStudy (anonymous):
(18-4+12/2) or 18-4+12/2 ?
OpenStudy (notamathgenius):
Its order of operations so addition has to be put first
OpenStudy (anonymous):
18 – 4 + 12 / 2

Wouldnt you use PEMDAS?
OpenStudy (anonymous):
is it like this\[\frac{ 18-4+12 }{ 2}\]
OpenStudy (anonymous):
So the answer is 13? For some reason I thought you divide first
OpenStudy (anonymous):
yes it is 13
OpenStudy (anonymous):
Thank you!

You're welcome
OpenStudy (anonymous):
your problem is not correct that is why u did not get the answer
OpenStudy (anonymous):
i guess it is like this
\[\frac{ 18-4-12 }{ 2}=1\]
OpenStudy (anonymous):
My problem is correct though, this is the question
Simplify: 18 – 4 + 12/ 2
OpenStudy (anonymous):
Oh ok! So it should be 1.
