Do you mean:
- the multiplication 2 × 2 (answer: 4)?
- a 2×2 matrix (determinant, inverse, solve linear systems)?
- a 2×2 Rubik’s (Pocket) Cube (how to solve)?
- something else (a 2×2 image, tile, room, etc.)?
If you mean a 2×2 matrix [a b; c d]:
- det = ad − bc
- inverse (if det ≠ 0) = (1/det) [d −b; −c a]
Tell me which one (and give any numbers/entries) and I’ll proceed.
