2-2

If you meant the arithmetic 2 − 2, the result is 0. Reason: a − a = 0 for any a (here a = 2). If you meant “Section 2.2” or “Problem 2-2” from a textbook, please share the exact problem statement or topic (e.g., calculus, algebra), and I’ll help you solve it step by step. I can also provide similar practice problems.
