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

The standard order of operations:terms inside bracketsexponents and rootsmultiplication and divisionaddition and subtraction

The standard order of operations follows the acronym PEMDAS. This is Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So operations are done on expressions within parentheses first.

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.

A standard order of operations lets you know which part of the equation gets calculated first. Without a standard order, someone might calculate 2 + 3 * 4 differently from 4 * 3 + 2, getting 20 in the first case and 14 in the second (by the way, 14 is the correct answer for both by the commonly accepted order of operations).

You memorize the rules that are considered standard.

Calculating could be confusing and leading to an incorrect answer.

It wouldn't be what it is unless if it didn't have to be that way

If you put in parentheses, you can change the order of operations in many cases, as parentheses come before everything in the order of operations.

It means that the calculator can follow the order of operations and do the order of operations for you but, you need to know how to do them on your own too.
