Matrix Multiply by Scalar

What, in relation to matrices, is a Scalar?

• rate-of change-of measurement i.e.
   "5m/s²"

• scaly pet i.e.
  "A Pygmy Alligator"

• single value i.e.
  "80"

• Their is no such thing as a scalar i.e. 

What do m, n, p and q equal in this scalar matrix multiplication?

• m=8, n=9, p=-4, q=4 

• m=15, n = -45, p=20, q=-5

• m=20, n=-5, p=15, q=-45

• m=-5, n=20, p=-45, q=15

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
