Question
Write the additive inverse of matrices A, B and C:
Where `A = [(6, -5)]; B = [(-2, 0),(4, -1)]` and `C = [(-7), (4)]`.
Solution
We know additive inverse of a matrix is its negative.
Additive inverse of A = –A = `-[(6, -5)] = [(-6, 5)]`
Additive inverse of B = –B = `-[(-2, 0),(4, -1)] = [(2, 0),(-4, 1)]`
Additive inverse of C = –C = `-[(-7),(4)] = [(7),(-4)]`
