PEMDAS, Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction, is a mnemonic for the order of operations in any mathematical expression, not just those in algebra.
Perhaps "Wright or Wrong: Teaching the Order of Operations" (Schrock & Morrow, 1993) is the earliest publication of the mnemonic.
The standard order of operations has been around a very long time, of course. I seem to vaguely remember this mnemonic from the 70s or 80s, but it was presented as a flawed, misleading device (e.g multiplication is really same order of precedence as division, and addition is same order of precedence as subtraction), so I never relied on it. I'm not confident in that recollection, anyway

When doing a math problem which of the calculations is done first?
Remember PEMDAS. It stands for Parenthesis,Exponents,Multiply, Divide, Addition, and finally Subtraction. If they are already in order then just start at the left and go to the right.
Why do you start from the left when comparing whole numbers?
