    Need help with integer Problem

    I was assigned two of these problems for my homework, and i have no clue what i am suppose to do. These are typed exactly as they appear on my worksheet. Any help would be greatly appreciated.

    1.)

    (+ + 5 - - 4 + - 5) - (+ - 2 + + 6) - (7 + 4 + -5)

    2.)

    (+ - 6 - - 5 + 6) - (- - 7 + - 4 + 6) - (- - 8 + - 5 - + 7)

    Lacking any instructions or definitions, I'm afraid I have no idea what you're supposed to do, either!

    It looks as if you are to simplify:
    Since a double negative = a positive and since + is normally assumed and not explicitly written:

    (+ + 5 - - 4 + - 5) - (+ - 2 + + 6) - (7 + 4 + -5)

    The symbols in blue denote operation while the symbols in red denote the sign of the number.


    ( 5 + 4 - 5) - ( -2 + 6) - (7 + 4 -5)

    extend the operation across the parenthetical value

    ( 5 + 4 - 5) - - 2 -+ 6 - 7 -+ 4 --5

    double negatives = + and then remove positive signs

    5 + 4 - 5 + 2 - 6 - 7 - 4 + 5

    All of the numbers are positive and the plus/minus signs now are operations.

    I do not have a high performance computer available to calculate that sum.

    It looks as if that is what is wanted.
