If x and y are negative rational numbers, then so is x + y

Solution:

Let the rational numbers be x, y: -2, -3

x + y = -2 + (-3) = -2 - 3 = -5

x + y = -5 which is a negative rational number.

✦ Try This: If x and y are positive rational numbers, then so is x + y.

Let the positive rational numbers be 3, 4

x + y = 3 + 4 = 7 which is positive
