Why is the order of operations important?
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.
What is commutative and associative in math?
A binary operator is a mathematical operator that performs some operation (eg addition, multiplication) on two operands to produce a result. Commutativity is the property of some binary operations whereby, the order of the operands does not matter. For example, a + b = b + a Associativity is the property of some binary operators whereby, if there is a sequence of such operations, the order in which the operations are carried out does not matter. However, the order of the operands may affect the result. For example, (a + b) + c = a + (b + c) and so we may write them simply as a + b + c.
What is the reason for the order of operations?
Those are conventions. Many people have gotten accustomed, over the years, to doing operations in a certain order. You can invent your own set of rules, but those would have to be clearly stated to avoid confusion... and it would serve no useful purpose. Having SOME order of operations defined is useful, to avoid having to write parentheses any time you have more than one operation.
Why is exponents second in the order of operations?
It is because of convention. It was necessary for some order of operation to be agreed so that wo people carrying out the same calculation would come to the same answer.
What do associative mean in a math term?
A binary operator is a mathematical operator that performs some operation (eg addition, multiplication) on two operands to produce a result. Associativity is the property of some binary operators whereby, if there is a sequence of such operations, the order in which the operations are carried out does not matter. However, the order of the operands may affect the result. For example, (a + b) + c = a + (b + c) and so we may write them simply as a + b + c.
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.
Why is the order of operations important?
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.
Why is there an order of operations in math?
Because without an agreed upon order, some calculations would yield ambiguous results.

it is ok in some occasains but you might want to retry the problem
