In mathematics, a matrix (plural: matrices) is a rectangular array or table of numbers, symbols, or expressions arranged in rows and columns. It is used to represent a mathematical object or describe properties of such objects. Matrix Operations: Adding or Subtracting Two Matrices: A matrix A with 3 rows and 5 columns can be added to another matrix B of the same dimensions (3 rows and 5 columns). To perform addition or subtraction, the two matrices must have the same size, meaning the rows and columns must match. Multiplying Two Matrices: To multiply an m×n matrix by an n×p matrix, the number of columns in the first matrix (n) must equal the number of rows in the second matrix (n). The resulting matrix will have dimensions m×p: m×n×n×p=m×p Dividing Two Matrices: Matrix division is defined as: A/B = A × (1/B) = A × B⁻¹ Where B⁻¹ is the inverse of matrix B.
