A) Since matrix A is , this means that




B) The additive inverse of matrix A (let's call matrix B) will have elements that are additive inverses of the elements of matrix A. So the matrix is




Note: simply change the signs of each element in matrix A to get matrix B.


Notice how which is the zero matrix. So this confirms our answer.
