In a third order determinant, each  element of the first column consists of  sum of 2 terms, each element of the  second column consists of sum of 3 terms  and each element of the third column  consists of sum of 4 terms. Then it can  be decomposed into n determinants,  where n has the value  Ans= 24

2×3×4  e.g     [((a+b),(c+d)),((e+f),(g+h)) ]   =  [(a,(c+d)),(e,(g+h)) ]+ [(b,(c+d)),(f,(g+h)) ]   =  [(a,c),(e,g) ]+ [(a,d),(e,h) ]+ [(b,c),(f,g) ]+ [(b,d),(f,h) ]
2×3×4e.g[a+bc+de+fg+h]=[ac+deg+h]+[bc+dfg+h]=[aceg]+[adeh]+[bcfg]+[bdfh]
