what is the difference between the symbol of modulus and the symbol of determination in matrix?​

Answer 1

Answer:

Determinant, in linear and multilinear algebra, a value, denoted det A, associated with a square matrix A of n rows and n columns. Designating any element of the matrix by the symbol arc (the subscript r identifies the row and c the column), the determinant is evaluated by finding the sum of n!
