Question 498087: Give the counterexample for the following:
If you subtract -2 from -6, themm the result is -4.
*I'm pretty sure this isn't proofs exactly yet but we have to learn this before we start proofs and I don't understand how to do it. I didn't know what other category to put it under.

There is no counterexample because -6 - (-2) is always -4. A counterexample would assert that there is a possibility that -6 - (-2) is not -4.

In general, a counterexample is a case where a theorem fails. For example, the statement "(2*3*5*7*11*...*p) + 1 is prime" has a counterexample where p = 13, because (2*3*5*7*11*13) + 1 = 59*509 and is therefore not prime.
