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.
