Exponents and parentheses

Formulas also support more complex operations, including exponentiation and parentheses. Exponentiation allows you to create formulas where one number is placed to the power of another number, and parentheses means you can control the order that operations are executed.

In formulas, operations are executed in the following order, from first to last:

• Parentheses
• Exponents
• Multiplication and division
• Addition and subtraction

In this exercise, you'll use your knowledge of formulas and order of operations to calculate the new prices for each item, which are calculated by adding 0.2 to the existing Price, then raising to the power of 2.
