Matrices are key concepts in mathematics, widely used in solving equations and problems in fields like physics and computer science. A matrix is simply a grid of numbers, and a determinant is a value calculated from a square matrix.
Example: \begin{bmatrix} 6 & 9 \ 5 & -4 \ \end{bmatrix}{2\times 2}, \begin{bmatrix} 3 & -4 & 5 \ 1 & 7 & 6 \ 6 & -2 & 9 \\end{bmatrix}{3 \times3}
Example: \begin{bmatrix} 6 & 9 \ 5 & -4 \ \end{bmatrix}{2\times 2}, \begin{bmatrix} 3 & -4 & 5 \ 1 & 7 & 6 \ 6 & -2 & 9 \\end{bmatrix}{3 \times3}
