Do you mean [(5-3)3 + 12]/4 ?

Answer: [(5-3)3 + 12]/4 = (8+12)/4 = 5

You need to use order of operations (PEMDAS)

   (5-3)3 +12/4

= 23 + 12/4     Everything in Parentheses must be done first, using PEMDAS.

= 8 + 12/4      Exponents is done next.

= 8 + 3           Next is Multiplication and Division from left to right.

= 11               Finally, Addition and Subtraction from left to right.

PEMDAS is a mnemonic: Please Excuse My Dear Aunt Sally.
