For this exercise, we have 4, negative 2, 0, 2, and 2.
00:12
Then we have 5, negative 2, 1, and 7.
00:18
Then we have 3, 4, negative 1, and 3.
00:26
So what we're going to do is get rid of our first column 0.
00:32
So this is going to be 5 row 1 minus 4 row 2, 3 row 1 minus 4 row 3.
00:41
So this row will stay the same for now.
00:49
This row we have 0.
00:52
Negative 10 minus negative 8 is negative 10 plus 8.
00:56
That's negative 2.
00:58
0 minus 4 is negative 4.
01:02
10 minus 28 is negative 18.
01:08
12 minus 12 is 0...
