2-2

Do you mean the arithmetic expression 2 − 2? If so, the result is 0. Reason: 2 minus 2 equals 0 (2 + (-2) = 0). If you meant something else labeled “2-2” (e.g., a problem number from a textbook or an exam section), please share the full problem statement or the context, and I’ll walk you through it and provide a solution. I can also generate related practice problems if that helps.
