In India , We refer it as PBODMASPEMDAS
Parenthesis, Exponents, Multiplication and Division in the order they occur from left to right in the problem, Addition and Subtraction in any order.
Powers or indices rule of evaluation, Brackets/Parenthesis, OF(not necessary though, it is way of showing "x"), Division , Multiplication , Addition and Subtraction.
the trouble with PEMDAS (or PBODMAS) is that one can never be confident the originator of the expression was actually thinking along the same lines....
for this reason, division is evil, and should be banished as a concept from our minds. multiplication may be given a reprieve, but only if it behaves itself.
subtraction has similar problems, and i am inclined to only tolerate it for its brevity.
