(-9) + (-11) > (-9) - (-11).
False
False.
(-9) + (-11) = -9 - 11 = -20 [Adding the negative of a positive number is subtracting that positive number]
and (-9) - (-11) = -9 + 11 = 2 [Subtracting the negative of a positive number is adding that positive number]
So, (-9) - (-11) is greater than (-9) + (-11).
