Matrices

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: [Tex]\begin{bmatrix} 6 & 9 \\ 5 & -4 \\ \end{bmatrix}_{2\times 2}[/Tex], [Tex]\begin{bmatrix} 3 & -4 & 5 \\ 1 & 7 & 6 \\ 6 & -2 & 9 \\\end{bmatrix}_{3 \times3}[/Tex]
