2-2

0 If you meant something else by "2-2" (for example a problem 2.2 from a chapter, or a different operation), please share the full statement or the subject area and I’ll help you work through it. Quick tip: 2 - 2 = 0 because subtracting a number from itself gives zero (a - a = 0). If you’d like, I can generate similar practice problems or walk through related concepts (e.g., solving equations, simplifying expressions).
