00:00:12,030 --> 00:00:13,650
Hi, everybody, and welcome.

2
00:00:13,860 --> 00:00:22,350
So in this lecture, we will try to answer your homework regarding integer and fourth variables, so

3
00:00:22,650 --> 00:00:26,280
please open your project that we started at the beginning of the course.

4
00:00:26,670 --> 00:00:34,530
And then after it's open, you probably pretty much remember just click file and open and then choose

5
00:00:34,530 --> 00:00:38,580
your destination, you meaning your project right here.

6
00:00:38,580 --> 00:00:41,910
And once you see the square here, just double click on it.

7
00:00:43,170 --> 00:00:43,710
All right.

8
00:00:44,100 --> 00:00:44,970
Before we begin.

9
00:00:45,000 --> 00:00:50,520
Guys, I just want to remind you guys that each lecture has attachment files with everything that we

10
00:00:50,520 --> 00:00:51,420
are studying here.

11
00:00:51,660 --> 00:00:54,270
So you can have it as files on your computer.

12
00:00:54,270 --> 00:00:55,990
So you could practice it later as well.

13
00:00:56,580 --> 00:00:56,860
All right.

14
00:00:56,860 --> 00:01:06,270
So once we are up, let's just click on the project file and you can create a new file called Integer

15
00:01:07,020 --> 00:01:08,220
and Float.

16
00:01:11,930 --> 00:01:12,670
Practice.

17
00:01:13,970 --> 00:01:14,600
All right.

18
00:01:20,460 --> 00:01:28,860
By the way, guys, this is a good practice to always leave notes for times that you going to get back

19
00:01:28,860 --> 00:01:35,940
to these files from time, from some time from now, and you would know what's going on and these notes

20
00:01:35,940 --> 00:01:36,680
really helpful.

21
00:01:36,720 --> 00:01:37,020
All right.

22
00:01:37,890 --> 00:01:39,120
So let's begin, guys.

23
00:01:39,450 --> 00:01:43,200
First of all, let's try to set all the values.

24
00:01:43,230 --> 00:01:45,030
So, first of all, is gross.

25
00:01:46,310 --> 00:01:47,030
Paycheck.

26
00:01:49,060 --> 00:01:54,160
Which is ten thousand dollars that we have health.

27
00:01:56,440 --> 00:02:07,060
Insurance, which is five hundred thirty eight ninety nine, and then we have rent, twelve hundred

28
00:02:07,060 --> 00:02:15,070
and food, we get a discount of half a dollar and then we have tax.

29
00:02:17,190 --> 00:02:23,190
All right, guys, about tax here writes it zero point two, but John, don't remember that this is

30
00:02:24,270 --> 00:02:24,780
in.

31
00:02:26,350 --> 00:02:30,910
Percent's right, this is not a numeric value for money.

32
00:02:31,120 --> 00:02:39,100
It stands four percent and last headline donation for the poor.

33
00:02:41,340 --> 00:02:46,290
And this one is zero point one, and it's also in percent.

34
00:02:50,750 --> 00:02:53,690
All right, so first of all, let us.

35
00:02:57,660 --> 00:03:06,900
Calculate net salary, so the basic math that we need to do here is to, first of all, create a new

36
00:03:06,900 --> 00:03:14,460
variable net salary and that would equals here and will back it will be back in it in a minute, but

37
00:03:14,460 --> 00:03:15,350
before it.

38
00:03:15,810 --> 00:03:18,660
And first, let us create a tax.

39
00:03:20,270 --> 00:03:30,530
Amount in money and do equals here and at stake, the gross salary, the gross paycheck and multiplied

40
00:03:31,550 --> 00:03:40,310
on donation, no, not donations, saurian tax and this would be the tax deduction that we need to do

41
00:03:40,310 --> 00:03:42,920
from our gross paycheck in here.

42
00:03:43,280 --> 00:03:48,080
So this is like a pre calculation for the main mission of our task.

43
00:03:49,550 --> 00:03:57,230
So we have a gross paycheck and let's deduct tax amount in money.

44
00:03:57,830 --> 00:04:02,990
It's right here in the pop up unter and health insurance.

45
00:04:04,710 --> 00:04:08,010
And rent them food.

46
00:04:09,060 --> 00:04:20,670
All right, so let's print it, and this would be our net salary and let's do a plus here.

47
00:04:21,030 --> 00:04:28,350
And as you recall from previous lectures, as we have a print here so we can have only one type here

48
00:04:28,350 --> 00:04:29,150
instead of print.

49
00:04:29,430 --> 00:04:31,660
So here we have a string.

50
00:04:32,100 --> 00:04:32,510
All right.

51
00:04:32,520 --> 00:04:35,340
But now we want to insert a number in here.

52
00:04:35,820 --> 00:04:41,320
But it will give us an error, of course, because we have a integer and here we have a string.

53
00:04:41,640 --> 00:04:50,160
So what we need to do is to convert it to string, uh, with a special keyword and brackets around it.

54
00:04:50,520 --> 00:04:52,290
And let's try to print it.

55
00:04:55,480 --> 00:04:56,200
All right.

56
00:04:57,570 --> 00:05:04,520
So there you have it, this is Yonath salary, reduced all of the expenses, including tax in percents

57
00:05:04,530 --> 00:05:05,610
that we did right here.

58
00:05:06,750 --> 00:05:07,140
All right.

59
00:05:08,200 --> 00:05:15,360
So let's go further to calculating the donation to poor.

60
00:05:16,830 --> 00:05:17,940
Taken from.

61
00:05:20,010 --> 00:05:20,930
That salary.

62
00:05:22,230 --> 00:05:30,840
So as you can guess, we already did some kind of math action here that is really similar, of course,

63
00:05:30,930 --> 00:05:38,940
regarding the donation amount, and I would like you to try to guess what is the similar math calculation

64
00:05:38,940 --> 00:05:45,840
that we did in this call that is really similar to calculating the donation to the poor out of the net

65
00:05:45,840 --> 00:05:46,320
salary?

66
00:05:48,930 --> 00:05:53,350
All right, so this is the answer, guys, because it's the same thing here.

67
00:05:53,700 --> 00:05:56,520
This is in percentage and this is also in percentages.

68
00:05:56,520 --> 00:05:59,880
So the calculation would be similar, right.

69
00:06:00,930 --> 00:06:13,890
So we just need to make a new variable called donation amount equals and then take our net salary and

70
00:06:13,890 --> 00:06:17,070
multiply it with a donation to the poor.

71
00:06:19,020 --> 00:06:24,540
And that sprint it sprint and then donation.

72
00:06:26,620 --> 00:06:29,920
Amount in money.

73
00:06:31,490 --> 00:06:32,690
Will be plus.

74
00:06:34,920 --> 00:06:42,120
Donation amount and also we need to make it a string, as we did before.

75
00:06:43,540 --> 00:06:45,550
All right, so it's printed.

76
00:06:46,290 --> 00:06:47,400
So there you have it.

77
00:06:47,430 --> 00:06:49,120
So this is the donation amount.

78
00:06:49,290 --> 00:06:50,400
It's not the amount.

79
00:06:50,730 --> 00:06:51,510
It's amount.

80
00:06:54,180 --> 00:07:00,540
So this is the donation amount and calculated out of the net salary.

81
00:07:00,990 --> 00:07:02,490
And that's about it, guys.

82
00:07:02,500 --> 00:07:06,330
So we had a mixture here of all concepts regarding numbers.

83
00:07:07,140 --> 00:07:09,120
And we have integer numbers here.

84
00:07:09,130 --> 00:07:10,650
We have a float numbers.

85
00:07:10,650 --> 00:07:15,680
We have pissants here and we have calculated the mix of them.

86
00:07:15,960 --> 00:07:23,250
So we have here float a float result and also you float result here because we can see it's numbers

87
00:07:23,250 --> 00:07:32,820
Bastad decimal and you can sleep calmly tonight because I assure you that now you know your stuff among

88
00:07:33,420 --> 00:07:35,220
integer and float variables.

89
00:07:35,400 --> 00:07:36,830
And that's amazing, guys.

90
00:07:36,830 --> 00:07:42,660
So it's great progress because it's a really important part of the course to know how to manipulate

91
00:07:42,660 --> 00:07:43,230
numbers.

92
00:07:43,650 --> 00:07:46,830
And I'm very happy that we are done with this part.

93
00:07:46,830 --> 00:07:49,110
And let's go over to the next topic.
