2-2

I’m not sure what you mean by “2-2.” Do you mean: - Problem 2.2 from your notes/textbook, or a section titled 2.2? - A simple arithmetic 2 − 2? - A specific course topic in Section 2.2 (e.g., Calc, Linear Algebra, Stats)? Please tell me the course and paste the exact problem or share the topic you’re studying. If you want, I can also give you a quick template for solving 2.2-style problems and then walk through a full solution once you provide the problem. If you just want the arithmetic: 2 − 2 = 0.
