If you don't, you'll get the wrong answer, because you'll perform the solution steps in the wrong order.

Because you can get the wrong answer if you don't. Consider this equation: 3 * x + 6 = 27 If you evaluate it properly, (3 * x) + 6 = 27 .. then the solution is: (3 * x) + 6 = 27 (3 * x) = 21 x = 7 If you evaluate the operations in the wrong order, as if it were: 3 * (x + 6) = 27 ... then you get: 3 * (x + 6) = 27 (x + 6) = 9 x = 3

The Order of Operations provides us with a fixed approach to solving algebraic expressions. Without them, it would be impossible to get the same results because everyone would solve algebraic expressions in their own unique way. With the Order of Operations, everyone who solves a given problem will arrive at the same solution(s). This is what makes it possible to tackle problems like predicting the orbit path of Mars so we can land a probe on it...or develop software that does your math homework for you.;)

2. The order of operations and other properties of mathematics are important because it provides a logical way to solve problems. If you happen to mess up part of the problem and you do follow correct methods you can go back to find your mistake. If you do not follow correct methods it will be much more difficult to find your mistake. Using the order of operations also makes sure that everyone who does the problem gets the same answer, unlike if everyone did it in their own way and all answers were different. This provides us with an absolute answer to a problem rather than having hundreds of answers for the same problem.

because if you dont use the order of operation (P parenthesis
E exponent
M multiply
D divide
A add
S subtract
) you will get the wrong answer

If not used, it changes the answer that you get. It insures that everyone gets the same answer from doing the same equation/problem.

PEMDAS is important because that is how the people who made up the concept wanted.
