One very powerful reason is: Order of operations is not something that you "do".

'Order of operations' is a rule, method of procedure, standard operating procedure,

and protocol, that guides you in the effective and correct way to actually "do" the things

that you "do" in arithmetic. The calculator is one place where you can 'do' them.

You do it wrong. With out order of operations, the same math problem could have several different answers. In math, there is only one answer.

It is convenient for different people to agree on the standard order of operations. This saves complicated explanations.

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Last year, my friends and I did a video on the Order of Operations to Rebecca Black's song Friday. It came out really well and we got a 100 on it. Here's a little bit of it: Addition and subtraction, multiplication and division. Gotta get the answers, what do we do now? It's the order order order of operations, everybody's looking forward to the math test, math test. order order order of operations, everybody's looking forward to the math test.
