Okay, we're going to do some work with converting values in this exercise.
00:05
First, we've got 100, but we want this 100 to be thought of, like, the numbers on a keyboard.
00:13
Just like the characters on a keyboard, just like a, b, c, you can turn them into asc representations.
00:19
So, again, i'm looking at appendix a.
00:22
Appendix a in the textbook will take these characters, or these characters on a keyboard, and turn them into binary representations.
00:31
So i'm going to go ahead and show this out.
00:34
If we have the number one, and i'm looking at appendix a, number one can be represented like this.
00:40
0 -0 -1 -0 -0 -0.
00:44
That's what number one can be represented as.
00:47
Right next to it is the number zero, which can be represented as this.
00:53
And to do the last part, we just need another zero.
00:56
So that's another zero right here.
00:59
I'm doing a little space in between each four digits so that they're easy.
01:04
To read.
01:05
But this is our answer for the first step.
01:09
The second step is interesting.
01:10
The second step asks us to take the number 255 and turn it into binary.
01:16
So first what i want to talk about is the fact that in binary, if you're starting with a very simple zero or one, they, you know, that translates to a regular zero and one in the way we're used to looking at it.
01:29
But if you have a one and a zero, that is the next step up.
01:36
That translates to a two based on how we normally think about it.
01:40
This, speeding right along, this is going to be a four, and this is going to be an eight.
01:49
So i want to stop here and talk about that eight.
01:54
Everything is zero except for this place right here.
01:57
Normally, this would be the thousand's place, but since this is binary we're talking about, this is actually called the eight's place.
02:03
Over here, this one's the fours.
02:06
This is this is the two's place and this is our regular ones place...
