WebFormally, the determinant is a function \text {det} det from the set of square matrices to the set of real numbers, that satisfies 3 important properties: \text {det} (I) = 1 det(I) = 1. \text {det} det is linear in the rows of the matrix. \det (M)=0 det(M) = 0. The second condition is by far the most important. WebOct 4, 2024 · In mathematics, the expression 3! is read as "three factorial" and is really a shorthand way to denote the multiplication of several consecutive whole numbers.
