WEBVTT 00:00.240 --> 00:01.260 Shell of her log orders. 00:01.260 --> 00:02.820 This is the second exercise. 00:02.870 --> 00:06.730 So the case that you haven't already watched the deal with it all. 00:06.840 --> 00:08.800 Or you didn't do the first sahlins. 00:08.820 --> 00:11.180 I'd recommend that you go right now and start to watch. 00:11.490 --> 00:16.550 So the goal here is to convert the number from binary to decimal. 00:17.510 --> 00:21.560 This is a symbol but the very important procedure in the algorithmic way of thinking that we can learn 00:21.560 --> 00:23.480 from this is the program is priceless. 00:23.480 --> 00:26.090 So for you though Don have any ideas about buying that. 00:26.090 --> 00:26.610 No. 00:26.690 --> 00:30.720 I said is that you quantitate because it will create more than one program with them. 00:30.730 --> 00:35.150 The idea is very simple binary number of consist of year olds and what's. 00:37.100 --> 00:43.720 With that in mind it is very different to any present seeks in the decimal point in the binary way to 00:43.730 --> 00:47.890 0 1 1 0 0 0. 00:48.500 --> 00:51.410 I know that this is confusing but bear with me. 00:51.410 --> 00:52.980 Everything will become clear. 00:53.000 --> 00:59.150 I mean it there once in zeros our test has suites that show if someone exists or not. 00:59.180 --> 01:01.650 The important part is where did the zero end. 01:01.650 --> 01:02.800 ONE HOUR. 01:07.960 --> 01:12.500 So the zero position that you present the tool in the power of zero. 01:12.610 --> 01:18.320 The first position is still in power of one and so on and so forth. 01:20.420 --> 01:21.850 So is a previous example. 01:21.890 --> 01:23.440 The first point is zero. 01:23.600 --> 01:27.230 So zero multiplied by two about Brazil. 01:27.290 --> 01:33.420 The second one is 1 so 1 multiplied by talking about one in the third one. 01:33.440 --> 01:39.600 He's also one saw one multiplied by two walking the part of two and all the rest are receding. 01:41.460 --> 01:50.470 So tilting the part of one piece equal to two end to the power of all is equal to four. 01:50.520 --> 01:54.610 Finally we multiply these two numbers and the result are six. 01:56.710 --> 01:57.710 Let's try it again. 01:57.880 --> 01:59.870 Let us have this number. 02:02.850 --> 02:13.830 This means that one multiplied by two above zero then would have two zeros into one in the bar of three 02:14.610 --> 02:17.130 and one again in the par of four. 02:17.130 --> 02:20.020 Of course because here is 0 1 2. 02:21.320 --> 02:24.110 Siri four five and six. 02:27.750 --> 02:29.770 If we are at this point. 02:31.210 --> 02:33.250 We get to the number 25. 02:34.850 --> 02:40.370 So we will agree with that program that calculate this number just by giving it by an army of the user's 02:40.370 --> 02:41.770 choice.
