OpenStudy (zale101):
first solve the parenthesis
OpenStudy (zale101):

OpenStudy (anonymous):
no. can you do it as an example?
OpenStudy (zale101):
(8-2) is the parenthesis and if you see that in an equation, solve it first

32 + 6 x 4 - 6/3?
OpenStudy (zale101):
ok, now the next step should be the exponents, but we don't see any exponents so let's just skip that, Ok now let's do the multiplication part, can u do that?
OpenStudy (anonymous):
32+24-6/3
OpenStudy (zale101):
good, now let's start do the divide, wait. There's no division, let's skip that. So move on to addition, do that.
OpenStudy (zale101):
oh my bad, there's division

wow.... the 32 was supposed to be 3 to the second power... haha my b yo
OpenStudy (anonymous):
thanks for your help i got it now:)
OpenStudy (zale101):
It's an order of operations problem
OpenStudy (zale101):
First you deal with the parenthesis
32 + (8 - 2) x 4 - 6/3 = 32 + 6 x 4 - 6/3
Next you deal with the x and /
32 + 6 x 4 - 6/3 = 32 + 24 - 2
Finally, you deal with the addition (+ )and and subtraction (-) in order
32 + 24 - 2 = 56 - 2 = 54
OpenStudy (zale101):
what are the choices?

yea i know but i was SUPPOSED to put 3 to the second power + (8-2) x 4 - 6/3, vs 32 + 6 x 4 - 6/3
