What do a, b, c and d equal in this matrix addition?

• a = -1, b = 10, c = 7, d = -11

• a = -1, b = 10, c = -11, d = 7

• a = 10, b = -1, c = 7 , d = -11 

• a = 10, b = -1, c = -11, d = 7

How would a scalar multiplication be carried out for a matrix?

• Add the Scalar to every element in the matrix

• Dot product the rows of one matrix with the columns of the other matrix

• Multiply every element with the scalar to create a new matrix

• subtract the elements in the first matrix from the elements of the second matrix
