OpenStudy (anonymous):

well MDAS would be the multiplication, division, addition, and subtraction

OpenStudy (anonymous):

OpenStudy (anonymous):

then 3*2

OpenStudy (anonymous):

120

OpenStudy (anonymous):

ok 120 good

OpenStudy (anonymous):

which will give you 120/12 - 4

OpenStudy (anonymous):

i mean 120/6 - 4
