2-2

0

Reason: 2 − 2 = 0. If you’re studying for exams, remember subtracting the same number yields zero (on a number line you’d move the full distance left to 0).

Want a few similar practice problems, or a quick recap of subtraction rules (including negative results and borrowing)? Or did you mean a specific problem labeled “2-2” (e.g., Chapter 2, Problem 2)?
