Accepted Answer

A 2×2 matrix is a rectangular array of four numbers arranged in 2 rows and 2 columns. Matrix operations including determinants, inverses, addition and multiplication are fundamental in linear algebra, computer graphics, and data science.

💡

Tip: A matrix has an inverse only when its determinant is non-zero.

Question 2

How does the Matrix 2×2 Calculator work?

Accepted Answer

Determinant: det(A) = ad − bc for [[a,b],[c,d]] Then: Inverse: A⁻¹ = (1/det) × [[d,−b],[−c,a]] Then: Addition: add corresponding elements Then: Multiplication: row × column dot products.

Question 3

Can you give an example of how to use the Matrix 2×2 Calculator?

Accepted Answer

Example: Input A = [[1,2],[3,4]] gives a result of det(A) = −2; A⁻¹ = [[-2,1],[1.5,−0.5]].
