Many expressions involve two or more operations. When simplifying such expressions, it is important to perform the operations in the following order:
1. Perform any operation(s) within group symbols, which are:
a. parentheses ( )
b. brackets [ ]
c. braces { }
d. fraction bar /
e. absolute-values bar | |
f. radical sign
2. Simplify all powers.
3. Multiply and divide in order from left to right.
4. Add and subtract in order from left to right.
If you don't follow this order of operations, you will find a wrong answer.

Because if you perform the operations in a different order your answer will be wrong.
You do it wrong. With out order of operations, the same math problem could have several different answers. In math, there is only one answer.
Order of Operations is like when you have a problem i always use PEMDAS it means parenthesis, expoents, mulitipication, divide, addition, Subtraction follow it.
