please i need answer
assuming am having a 3 by 3 determinant
[a+b c+p m+w]
[b+m v+r r+d. ]
[c+d r+p e+w]
can i say
[a c m] [b p w]
[b v r ]. +[m r d ]
[c r e ] [d p w]
If you're adding matrices, then the top matrix is the sum of the bottom two matrices.
But determinants do not work like that.
You cannot take determinants and then add them. Look at just the first term of the values:
(a+b)(v+r)(e+w) ≠ ave + brw
