    1+1=2

    -1 +1 =0

    -1 + -1 = -2

    -(1) + -(1) = 1

    1 x 1 = 1

    -1 x -1 = 1

    -1 x 37 = -37

    1 x -37 = -37

    1 + -37 = -36 yes, its right

    -1 + -37 = -38 yes, its right

    -1 + -1 = -2

    -(1) +-(1) = -2

    -1 x -1 = 1

    -1 x 37 = -37

    1 x -37 = -37

    Last two are correct.

    -1+-1=-2

    -(1)+-(1)=-2

    -1x-1=1

    -1x37=-37

    1x-37=-37

    A negative multiplied by a negative is a positive.

    A negative times a positive is a negative.
