multiplication goes first
There is pneumonic:
Please Excuse My Dear Aunt Sally (PEMDAS) is a mnemonic (memory aid) that helps you remember which operation comes first, which comes second, and so forth. P parentheses E exponents, M multiplication, D division, A addition , S subtraction.
I am yet not sure of correct answer!
= 4-4-4-4+4+(4x4)-4-4 (multiplication first)
