In this question, we're imagining that cells all have addresses that are two hexadecimal digits long.
00:08
It would start out on the left.
00:10
It would start out with 0 .0 .01.
00:13
And it continued to that pattern all the way down to ff.
00:18
You can see that i've also written 0f and 1 .0.
00:21
I want to make a mention of that real quick.
00:23
The value of f, in this case, in hexadecimal, the value of f is going to be 15.
00:30
And the value of 1 -0 in hexadecimal is going to be 16.
00:35
So you can tell the f -f is going to be a much bigger number.
00:38
Our first step is to figure out how much ff is.
00:41
There's two ways to do this.
00:43
You could convert everything back to binary and solve based on binary.
00:49
You could solve what this value is.
00:53
Or we could do it another way.
00:54
We could notice that the right f, the smaller version, stands for 15.
01:00
I mentioned this earlier.
01:02
This is actually 15 in the 1's place.
01:08
And we're not talking about decimal version, so we're not talking about 10's place.
01:12
We're actually talking about 16's place.
01:15
So i'll show you what this looks like.
01:19
The f on the left has a value of 15 times 16 to the first power...
