PEMDAS ParenthesesExponentMultiplyDivideAddSubtract

OpenStudy (ryuga):

yes

OpenStudy (welshfella):

for example to simplify (3 + 2) * 8 - 1 we would work out whats in the parentheses first: so its 5 * 8 - 1 now multiply comes before subtract so its 40 - 1 = 39

OpenStudy (ryuga):

see he gets it

OpenStudy (welshfella):

i'll start you off on the first one 42 + 3 − 2(3) do the multiply first -2(3) = -6 this gives 42 + 3 - 6

OpenStudy (ryuga):

but there are acceptions like 4+9-1 you will just solve it going right through

OpenStudy (welshfella):

now add 3 to 42 then subtract 6 from the result

OpenStudy (nuccioreggie):

ok so im confusedwhat the other 3 are @welshfella

OpenStudy (ryuga):

so 39

OpenStudy (nuccioreggie):

for the second one right

OpenStudy (welshfella):

no thats the answer to the first one. The definitions look wrong.

OpenStudy (nuccioreggie):

ok 6 is the answerfor the first one and whats the answer for the second one

OpenStudy (welshfella):

no 6 is not the answer to first one the answer is 45 - 6 = what?

OpenStudy (ryuga):

39

OpenStudy (welshfella):

for the 2nd one fisrt do the multiply 22 times 8 then the divide by 2 then add 2
