Describe the importance of the order of operations. Provide an example where the outcome is affected by using and not using parentheses.
What will be an ideal response?
The order of operations is a set of rules that specify the sequence in which arithmetic calculations are performed from left to right in the following order of importance. Parentheses can be used to ensure a lower-order operation is performed before a higher-order operation.
For example, in B2-A2/A2, to calculate percentage change, not including parentheses creates an error in the calculation because the division occurs first. The parentheses are needed to subtract first: (B2 A2)/A2.
