Simple answer - people would get different answers. When it comes to Arithmetic, there is just one correct answer and that comes by following the correct order of operations :-)
So as to work out mathematical problems in the correct order of operations
It's not important at all, unless for some reason you want to end up with the correct answer. If you do the operations in a different order, the result will be wrong.
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).
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.

The correct order for cleaning and sanitizing is: 1) remove debris and dirt from the surface, 2) wash the surface with soap and water, 3) rinse the surface with clean water, and 4) apply a sanitizing solution to kill germs and bacteria.

NO the idea is to get to the correct answer and not interpret the order the wrong answer may appear
It has nothing to do with agreement or negotiation. There's only one order of operations that leads to the correct outcome.

you need to because if you follow the order of operations then you will get the question correct. If you don't then you won't. Simple as that
Replace the variables with the correct values and calculate using the order of operations

9 is the correct answer due to order of operations. Other answers are incorrect.
