Sept. 14th/09

Today we learned about Scalar Multiplication and Matrix Multiplication. The first two Matrices we learned were easier to understand for me, but these two take some thinking, which is not always a bad thing.

We learned about the two-finger method, and I found this method to be quite easy to understand and it helped me with understanding how to do questions that envolve matrix multiplication.

Two-Finger Method:

This method is done by giving a 'thumbs up' with your left hand, than extending your index finger, while your right hand shapes the letter L.
