Matrix Calculator (2×2)
MathAdd, subtract, multiply 2×2 matrices and find determinant.
Matrix A
Matrix B
Matrix arithmetic operates on 2×2 matrices: addition and subtraction are element-wise, multiplication follows the dot-product rule, and the determinant of [[a,b],[c,d]] is ad − bc. The determinant reveals whether a matrix is invertible (non-zero) and appears in solving linear systems and transformations. This tool handles all four operations on two matrices.
