00:00:00.990 --> 00:00:03.980
So welcome to section eight,
this is the binary system and

2
00:00:03.980 --> 00:00:05.460
other number formats explained.

3
00:00:05.460 --> 00:00:07.440
Now just a bit of a disclaimer for

4
00:00:07.440 --> 00:00:11.060
this section, if you find it a little
rough going, don't be put off.

5
00:00:11.060 --> 00:00:13.560
This is actually a special section and

6
00:00:13.560 --> 00:00:16.900
really you don't need to understand it
fully to get the most out of python.

7
00:00:16.900 --> 00:00:18.740
So it's all about binary,

8
00:00:18.740 --> 00:00:21.970
it's gonna teach you what binary
is How to actually use binary.

9
00:00:21.970 --> 00:00:26.110
How to actually use addition, and
subtraction, et cetera with binary.

10
00:00:26.110 --> 00:00:29.740
And then we'll go into hexadecimal,
what that is as well as octal.

11
00:00:29.740 --> 00:00:32.820
And there will be a brief challenge
at the end to challenge you.

12
00:00:32.820 --> 00:00:35.520
So, have a go at it and
see how you get on, but

13
00:00:35.520 --> 00:00:39.560
again don't be too perturbed if you find
this particular section too complex.

14
00:00:39.560 --> 00:00:41.960
Things actually get easier
in the next section.

15
00:00:41.960 --> 00:00:45.590
But with that said, we felt,
both myself and Jean-Paul

16
00:00:45.590 --> 00:00:49.780
thought it was very important for you to
understand what binary is and how things

17
00:00:49.780 --> 00:00:53.340
work at a low level on a computer, and
that's why put this chapter together.

18
00:00:53.340 --> 00:00:54.310
So let's make a start
