The Order of Operations
And how to use it!
What IS the ORDER of Operations?
To remember order of operations we use PEMDAS or Please Excuse My Dear Aunt Sally. P stands for parentheses, which we work out first in the problem. In the problem 8+(3x6)-28, we would figure out 3x5 first, because it is in the parentheses. If there are no parentheses, skip and go on. E stands for exponents. These are the things we work out next in the problem. If there are no exponents, skip and go on. Now this part gets tricky. M and D stand for multiplication and division, but you do them in left to right order. Same goes for A and S which is add and subtract, left to right.
