    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.

    4-4-4-4+4+4x4-4-4
    = 4-4-4-4+4+(4x4)-4-4 (multiplication first)
    = +4-4-4-4+4+16-4-4
    = -4-4-4-4-4 +4+4+16 (change order of -ve and +ve numbers)
    = - 20 + 24
    = +4
