You can put this solution on YOUR website! In mathematics and computer programming, the order of operations (sometimes called operator precedence) is a rule used to clarify unambiguously which procedures should be performed first in a given mathematical expression.
Parenthesis, Exponent, Multiplication, Division, Add, and Subtraction also known
as: Please Excuse My Dear Aunt Sally (PEMDAS)
5 + [4 + ( 12-4) ÷ 2]
= 5 + [4 + (8)÷ 2 ]
= 5 + [ 4 + 4 ]
= 5 + 8
= 13
