Determine if conjecture: True or False

The difference between two negative numbers is always negative

We can prove it false with a counter-example

-4 - (-2) = - 4+2=-2, true

-2 - (-4) = - 2+4=2, not negative, that's our counterexample

false, the question sais 'always' but we found at least 1 instance where it is false and therfor it is a false statement
