The order of operations are rules that govern which mathematical operations are done first.

• Do operations in parentheses and other grouping symbols first. If there are grouping symbols within other grouping symbols do the innermost first.
• Do multiplication and division operations from left to right.
• Do addition and subtraction operations from left to right

Example: 2+3*(4+(6*3-8))*2
2+3*(4+(18-8))*2
2+3*(4+10)*2
2+3*14*2
2+42*2
2+84
86
