*The Inverse Property of Additionshows that if you add the opposite of a matrix and the matrix itself, the result will be the zero matrix.[A + (−A) = O] *The opposite, oradditive inverse,of matrix A is −A. −A is the matrix with elements that are the opposites of the corresponding elements of A. *The concept of equal matrices can help you find unknown matrix elements; if the two matrices are equal, their corresponding elements are equal. 03- Scalar Multiplication Vocabulary: Scalar- A real number used to multiply a matrix.
