To simplify the expression \(-2 - (-2)\), you can follow these steps:
- Recognize that subtracting a negative number is the same as adding the positive version of that number.
- Thus, \(-2 - (-2)\) can be rewritten as \(-2 + 2\).
- Now, calculate \(-2 + 2\), which equals \(0\).
So, \(-2 - (-2) = 0\).
