2-2

Do you mean: - 2 − 2 = 0 (simple arithmetic), or - Section 2.2 of a course/textbook (a specific problem)? If you meant the math, the answer is 0. If you meant a Section 2.2 problem, please share the course name, textbook, or the exact problem statement, and I’ll walk you through the solution step by step. I can also generate practice problems for Section 2.2 topics if you want.
