Multiplying a matrix by a constant scales every entry in the matrix by that constant:
![A=\begin{bmatrix}-3&5&2\\8&-1&3\end{bmatrix}\implies-6A=\begin{bmatrix}18&-30&-12\\-48&6&-18\end{bmatrix}](https://tex.z-dn.net/?f=A%3D%5Cbegin%7Bbmatrix%7D-3%265%262%5C%5C8%26-1%263%5Cend%7Bbmatrix%7D%5Cimplies-6A%3D%5Cbegin%7Bbmatrix%7D18%26-30%26-12%5C%5C-48%266%26-18%5Cend%7Bbmatrix%7D)
