What is
-16 + -8 x -2 -(4-9)= ?

I did it and got -72. I want to know if I'm right. I'm so confused with operations. Would you subtract the numbers and add, then multiply?

    Remember PEMDAS

    parentheses
    exponents
    multiply
    divide
    add
    subtract

    -16 + -8 x -2 -(4-9)=

    Parentheses: (4 - 9) = -5

    -16 + -8 x -2 -(-5)=

    Exponents: none

    Multiply: -8 * -2 = 16

    -16 + 16 -(-5)=

    Divide: none

    Add/Subtract

    -16 + 16 + 5 = 5
