Matrix multiplication using determinants

WebDeterminants. A determinant of a matrix represents a single number. We obtain this value by multiplying and adding its elements in a special way. We can use the determinant of a matrix to solve a system of simultaneous equations. For example, if we have the (square) 2 × 2 matrix: `((5,7),(2,-3))` Web18 jan. 2024 · If all elements of a row (or column) of a determinant are multiplied by some scalar number k, the value of the new determinant is k times of the given determinant. …
