The rule is to evaluate terms according the following order of priority:

In UK it is BIDMAS, an acronym for Brackets, Index, Division, Multiplication, Addition and Subtraction.

In US, it is PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition and Subtraction order of the mathematical order of operations."

Note, that multiplication and division have the same priority; also, addition and subtraction have the same priority.
