2-2

0 If you meant the arithmetic 2 − 2, the result is 0. This uses the idea that a number minus itself equals zero (the additive inverse property). If you meant a different problem labeled “2-2” (e.g., Section 2 Problem 2), please share the full statement and I’ll help solve it. I can also generate similar practice problems or explain related concepts (subtraction properties, additive inverses, etc.).
