1. 1Matrix addition/subtraction: add corresponding elements (matrices must be same size)
2. 2Matrix multiplication: row × column dot products (A must have same columns as B has rows)
3. 3Determinant (2×2): det(A) = ad − bc for [[a,b],[c,d]]
4. 4Transpose: flip rows and columns (rows become columns)
5. 5Inverse (2×2): A⁻¹ = (1/det) × [[d,−b],[−c,a]]
