Find the value of the expression. -128 divided by 4square plus 6 minus 1

  • college meth - ,

    i interpreted this as:
    -128 / 4^2 + 6 - 1
    recall PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. this is the order in which operation must be done first. therefore,
    -128 / 8 + 6 - 1
    -16 + 6 - 1
    -11

    hope this helps~ :)
