    So that's, because of BODMAS;
    -36 - 2(11) = -36 - 22 = -58

    what is BODMAS?

    It's the order of calculations.
    Brackets
    Other (alternatively Indices)
    Division
    Multiplication
    Addition
    Subtraction

    So, in your calculation, you'd do the brackets first, giving;

    -36 - 11 * 2

    From there, BODMAS applies, meaning you do the multiplication first, giving;

     -36 - 22 = -58

    Hope that made things a bit clearer.

    (-36)-(11)(2)
    -36-22
    = -58
    I believe

    Not being rude here, just logical: If you show me yours, I'll show you mine. If you want us to verify your answer, would a simple "yes" or "no" be enough of an answer for you? I'm personally OK with that, if that's really what you want. But if you want someone to type out a full solution, would you not best do the same as a matter of courtesy.

    As you see, "No" would have been appropriate here.
