In this question, we're going to encode the message, health is on the way using this encoding matrix.
00:08
So we'll go ahead and create 1 by 2 matrices from the original message.
00:15
So we'll take this from the letter to number system that we were given in the chapter.
00:22
So 8 is h, e is 5, l is 12, p, 16, space is 0, high is 9, s is 19, 0 is 15, and is 14, t is 20, 5, 0, w is 23, a is 1, and y is 25.
01:15
Now we'll take each of these matrices and multiply by the encoding matrix to get our message.
01:22
We'll start with 85.
01:25
It gets this negative 16, negative 21, and then 29...
