    -[4.2]


    Would it Be Negative 4.2 because it's the Absolute Value of 4.2 then you multiply that by -1? Or is it just 4.2 because the - Doesn't matter

    OK an example:

    10-4.2=5.8
    10-(4.2)=5.8.

    so basically the 4.2 becomes negative.
    And the - does matter.


    post the full question next time so that we can see the whole thing:)
