-6-(-5)=-1

Let's simplify the expression step by step:

1. Start with the expression: \(-6 - (-5)\).
2. Remember that subtracting a negative number is the same as adding its positive counterpart. So, \(-(-5)\) becomes \(+5\).
3. Therefore, the expression can be rewritten as: \(-6 + 5\).
4. Now, perform the addition: \(-6 + 5 = -1\).

So, \(-6 - (-5) = -1\) is correct.
