Definition of Order of Operations
The order of operations provides a list of rules that tell you the order in which to apply the operations that appear in a mathematical expression.
These rules are:
- Do everything inside brackets first (working from the innermost brackets outwards).
- Next, take powers of things.
- Next, multiply and divide, working from left to right when there is division involved.
- Finally, add and subtract.
For example,
\(
\begin{align*}
8 - (3 + 2) \times 6 + 4 \div 2 &= 8 - 5 \times 6 + 4 \div 2\\
&= 8 - 30 + 2\\
&= -20
\end{align*}
\)
