Section 7 : Mathematical Reasoning

  1. Consider

    x = - 1 y = - 2 (x and y are negative integers)

    - (x + y) = - (-1 - 2) = - (-3) = 3 i.e. positive

    - (x - y) = - (-1 + 2) = -1

    y - x = - 2 + 1 = - 1

    x - (-y) = - 1 - 2 = - 3

    x + y = - 1 - 2 = - 3

    \ - (x + y) is positive
