**bobpursley**, Thursday, September 17, 2009 at 11:06amThe language of Algebra is precise, and built into it is an expectation that the user will follow the order of operations rules. Going from left to right is not in those rule, and can lead to erroneous results.

P=parantheses E= Exponents M=Multiplication D=Division A=Addition S=Subtraction

It sounds stupid but it works.
