# Determinant Definition/Meaning:

A number associated with a square matrix of numbers. The determinant of an n x n matrix A is denoted by det(A) or |A| and given by

 ∑ par(s) a1ó1 a2s2......ansn s

where the sum is taken over all n! permutations

s = s1s2 ......sn

of the integers 1,2,... ,n. par(ó), the parity of s. is either +1 or -1 depending on whether s is an even permutation or an odd permutation.
