That is so there is no confusion on how something is worked out.
Eg 2 + 3 x 6 =
if we were to do that as it looks we would get 30 where as with the operations rule it would be 20.
So it serves to prevent confusion especially with very large calculations.

When evaluing expression with more than one operations?
In that case, you need to know the rules about which operations to do first. In normal algebra, powers have a higher priority than multiplications and divisions; and these, in turn, have a higher priority than addition and subtraction.
What is the rules for evaluating expressions?
The various operations within the expression are carried out using the order of operations: BIDMAS (UK) or PEMDAS (US).
What are the rules governing operations of real numbers?
There are different rules for different operations.
What is a set of rules used to evaluate more than one operation called?
order of operations
What is the sequence in which the operations will need to be carried out?
Operations are almost always carried out in the order of their importance to the task at hand.
In an order of operations problem if there is a parentheses do the order of operations rules apply in the parentheses?
yes
Why must the rules for the order of operations be understood before solving the equations in this section?
The answer will not be the same if you do not follow the order of operations. PEMDAS is the way most people remember it. It tells you what to do first and you need to know this to do the problems correctly. If not, you will often have the wrong answer.
An agreed set of rules to evaluate numerical expressions?
order of operations
What does mean if a calculator follows 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.
What are the rules in ordering operations?
You need to know it's functions and prices
What is the specific need for order of operations in Excel?
Computer are built on the laws of mathematics and so Excel must follow them. There are set rules for the order of operations that must be followed to ensure calculations are done in a consistent way. See the related question below.
How do you decide what operation you use in order of operations?
You memorize the rules that are considered standard.

In that case, you need to know the rules about which operations to do first. In normal algebra, powers have a higher priority than multiplications and divisions; and these, in turn, have a higher priority than addition and subtraction.
Why is it important to apply order of operations when evaluating expressions?
If you change the order of operations, you will get a different result. The person who wrote the expression had a specific order of operations in mind (using generally-accepted rules), so arbitrarily using some other order of operations is, quite simply, wrong.
