After that is done, then I can finally add in the 4: There is no particular significance in the use of square brackets (the "[" and "]" above) instead of parentheses. However, the operations may be called different things. BODMAS, BIDMAS and PEMDAS are acronyms for remembering the order of operations in mathematics. Elementary and middle school students generally use the acronyms PEMDAS or BEDMAS to help them remember the order in which they complete multi-operation questions. But the Order of Operations is only a set of rules for arithmetic! If everyone follows the rules, we’ll all be safe. I could add first: It seems as though the answer depends on which way you look at the problem. When there are several operations in a single expression, it's important to calculate them in the proper order (parenthesis first, exponents second...) to get the correct outcome.
