When a formula uses more than one operator, the order of operations in Excel is as follows:

Parentheses. Operations contained in parentheses (or brackets) are executed first.

Exponents. Exponents are executed second.

Multiplication / Division. Multiplication and division, which Excel treats equally, are executed third, from left to right.

Addition / Subtraction. Addition and subtraction, which Excel treats equally, are executed last, from left to right.
