1 00:00:00,480 --> 00:00:03,450 So now let's talk about the operators. 2 00:00:06,750 --> 00:00:12,990 So these operators perform the action on that variable content, addition, subtraction, etc., so 3 00:00:12,990 --> 00:00:18,190 that's going to find a variable here is equal to and and that's different. 4 00:00:18,210 --> 00:00:23,970 Another variable dollar B B equals 220. 5 00:00:24,570 --> 00:00:27,570 So now we can add some values to this. 6 00:00:27,570 --> 00:00:34,660 Word was used in this press operator that is the operator considerably plus. 7 00:00:36,720 --> 00:00:39,380 Now discuss the particular. 8 00:00:39,690 --> 00:00:47,760 But if you like the dollar, the value will be because we are adding the, uh, value of that extent 9 00:00:47,790 --> 00:00:53,100 and quality and we are not storing it in a dollar variable. 10 00:00:53,120 --> 00:01:03,110 So what we want to do is we want to say it is equal to the year plus 20 now instead of the start of 11 00:01:03,260 --> 00:01:03,540 the year. 12 00:01:03,630 --> 00:01:10,170 The value which is will placed here and the result will be performance and accountability will be assigned 13 00:01:10,170 --> 00:01:10,920 to this variable. 14 00:01:12,150 --> 00:01:15,040 Now, if you said already, it will be 30. 15 00:01:15,900 --> 00:01:18,150 So there is a shorthand notation for this. 16 00:01:18,660 --> 00:01:21,150 You can check dollar is equal to 10. 17 00:01:23,070 --> 00:01:27,270 So you can also say that the price is equal to 20. 18 00:01:27,720 --> 00:01:31,320 So what this means is equal should already oppressed. 19 00:01:31,740 --> 00:01:34,110 So this is the this shot her. 20 00:01:41,830 --> 00:01:49,810 So the shorthand notation for this is equal opportunity, so you can also set prices equal to 20, so 21 00:01:49,810 --> 00:01:52,020 it simply expands this one. 22 00:01:52,310 --> 00:01:56,730 So, uh, we don't know, let's bring this already. 23 00:01:56,920 --> 00:01:58,180 And it's very static. 24 00:01:59,440 --> 00:02:06,640 So in the same way, you can do the subtraction also, uh, at the very start to, uh, let's get out 25 00:02:06,640 --> 00:02:13,750 of here is equal to minus five sorority girls. 26 00:02:15,140 --> 00:02:17,800 So let's clear the screen. 27 00:02:18,670 --> 00:02:19,620 So, yeah. 28 00:02:19,870 --> 00:02:23,200 So there is value in variable has to define. 29 00:02:25,500 --> 00:02:34,260 So you can just start yet minuses to fight now to determine its fate, which is currently considering 30 00:02:34,260 --> 00:02:41,820 the value, which is not in the same way you could do the division and multiplication, also consider 31 00:02:42,060 --> 00:02:47,700 it is in state is equal to etc. So 32 00:02:50,840 --> 00:02:51,950 you'll get that order. 33 00:02:52,380 --> 00:02:53,800 So this is the shorthand tradition. 34 00:02:53,850 --> 00:02:56,890 You can also expand like story to tell. 35 00:02:58,650 --> 00:03:02,780 So there is also a division operator. 36 00:03:03,140 --> 00:03:05,130 Let's go ahead and the word button. 37 00:03:05,700 --> 00:03:08,400 So you'll get that as a reminder if you want to. 38 00:03:08,400 --> 00:03:15,180 The question, all you need to say is you need to put the percentage stands for a reminder. 39 00:03:15,250 --> 00:03:21,760 So upon 200 of our digital this county and the remainder zero. 40 00:03:21,780 --> 00:03:25,950 So this is model or you will get only that reminder. 41 00:03:26,790 --> 00:03:29,040 So these are the four basic operations. 42 00:03:29,040 --> 00:03:32,850 You can do the operation, multiplication and division. 43 00:03:32,850 --> 00:03:39,270 And also the reminder is not an operation, it's just an operation with a different result. 44 00:03:40,320 --> 00:03:43,290 So this is the basic arithmetic operations. 45 00:03:44,010 --> 00:03:47,330 So let's see the reason operations. 46 00:03:48,180 --> 00:03:57,990 So these relational operators perform on who are more values to where and with how the how these two 47 00:03:57,990 --> 00:03:59,780 areas are rated, et cetera. 48 00:03:59,920 --> 00:04:00,060 Yeah. 49 00:04:00,670 --> 00:04:05,190 And we have the two values in two hundred and twenty. 50 00:04:06,470 --> 00:04:09,120 No, I want to show you one more thing. 51 00:04:09,120 --> 00:04:17,170 That is, uh, that variable which you have seen in the previous videos and now there is will be proof. 52 00:04:17,230 --> 00:04:17,580 Yes. 53 00:04:17,730 --> 00:04:21,440 You can see here there is a variable called which transfer. 54 00:04:21,810 --> 00:04:22,370 Uh, true. 55 00:04:22,390 --> 00:04:26,140 This is the Boolean, uh, brilliant data type. 56 00:04:26,520 --> 00:04:30,900 So there are only two types in the true or false. 57 00:04:30,900 --> 00:04:34,230 The variable can help only to verify the true false. 58 00:04:34,260 --> 00:04:38,750 Here in this partial, it has already some system where that is true. 59 00:04:38,760 --> 00:04:42,050 And also there will be a forest so far as follows. 60 00:04:42,690 --> 00:04:52,740 So you can access this using data to get the value through and us and you'll get the files so you can 61 00:04:52,740 --> 00:04:57,850 compare some variables and you can check whether those conditions are true or not. 62 00:04:57,870 --> 00:04:59,240 So let's go ahead and do that. 63 00:04:59,910 --> 00:05:02,460 Now, let me bring the two variables. 64 00:05:02,460 --> 00:05:03,330 Uh, values. 65 00:05:03,330 --> 00:05:04,320 Two hundred twenty. 66 00:05:04,330 --> 00:05:04,640 Right. 67 00:05:04,890 --> 00:05:07,950 Let's so let's just for clarification. 68 00:05:07,950 --> 00:05:12,660 Let's bring those variables so we have two hundred and twenty and so that's it. 69 00:05:13,210 --> 00:05:13,550 Yeah. 70 00:05:13,950 --> 00:05:20,940 So whether I want to check whether you variable is greater than or equal to beat so I need to see you 71 00:05:21,820 --> 00:05:28,740 uh put the hyphen and greater than so distance or greater than Darbie. 72 00:05:29,190 --> 00:05:35,020 Now this returns, whether true or false, if he is greater than B is true, that it rings true unless 73 00:05:35,040 --> 00:05:36,090 it's false. 74 00:05:36,300 --> 00:05:37,530 So let's go on this. 75 00:05:37,890 --> 00:05:40,440 You can see true because two hundred is greater than forty. 76 00:05:40,440 --> 00:05:40,690 Right. 77 00:05:41,670 --> 00:05:45,280 So the RBA is greater than the sum is greater. 78 00:05:45,720 --> 00:05:54,160 So if you can also compare with greater than are equal to using E d greater than or equal to one as 79 00:05:54,180 --> 00:05:54,510 you can see. 80 00:05:54,510 --> 00:05:54,850 True. 81 00:05:55,830 --> 00:05:58,830 Now you can modify these values and check uh put. 82 00:05:58,830 --> 00:06:06,660 They put, they were used to twenty and then a sudden you get the uh because equal and change changes 83 00:06:06,660 --> 00:06:14,310 value to nineteen and you'll get the first so that I let you live up to four exercises, the values 84 00:06:14,310 --> 00:06:16,360 and put into the true of us. 85 00:06:17,040 --> 00:06:19,970 So now I can say less than less than adequate. 86 00:06:20,370 --> 00:06:25,040 So because false plus 200 is greater then and you can also say only less then. 87 00:06:26,190 --> 00:06:37,470 So and you can also verify equal to so other if its value is equal to two hundred or not. 88 00:06:37,590 --> 00:06:44,600 It's true because if I use two hundred let's say to not one now it says for us because it's two hundred 89 00:06:45,540 --> 00:06:52,590 now you can say not equal to using any, not any chance or not equal to the see true because it's values 90 00:06:52,590 --> 00:06:53,900 200 not to not one. 91 00:06:55,170 --> 00:07:01,290 So these are the relational apparatus greater than greater than equal to less than an equal to not equal 92 00:07:01,290 --> 00:07:01,480 to. 93 00:07:02,100 --> 00:07:07,980 So you can combine multiple comparisons using the, uh, logical apparatus. 94 00:07:08,280 --> 00:07:20,850 The lower end are, uh, not um, let's say, uh, the first uh, you can also compare like this, I 95 00:07:20,850 --> 00:07:23,080 forgot to tell you equal. 96 00:07:27,320 --> 00:07:34,610 So all of you, well, you must be one if I say is close to one, then if you compare it to it will 97 00:07:34,610 --> 00:07:41,900 be true because in computers one is four true when comparing and zero is four when comparing. 98 00:07:42,320 --> 00:07:48,010 And since use is one, if you compare with the true, this will become true. 99 00:07:49,520 --> 00:07:56,270 And if I say it is equal to zero, then if I compare it true, that will become false. 100 00:07:56,270 --> 00:08:01,670 Because, uh, Geto is, uh, indicator as a false comparison takes place. 101 00:08:02,780 --> 00:08:06,740 So that is you can also compare it to are false soreheads. 102 00:08:07,160 --> 00:08:15,280 Darayya Darbie, which print these, uh, variables values is equal to thirty. 103 00:08:16,700 --> 00:08:17,110 All right. 104 00:08:17,120 --> 00:08:21,660 Now we have to be and continually be and contain certain point. 105 00:08:21,770 --> 00:08:34,330 So let's combine these, uh, operators' operators year, uh, equal to Darbie. 106 00:08:36,570 --> 00:08:44,190 Right, which is for us now, we can see a logical end and order here. 107 00:08:47,810 --> 00:08:54,680 Not easy calls to, let's say, greater than Narangba, so now what you're going to do. 108 00:08:55,190 --> 00:08:56,750 First, we are comparing this one. 109 00:08:57,680 --> 00:08:59,450 It is equally to be or not. 110 00:08:59,900 --> 00:09:01,160 So, no, they are different. 111 00:09:01,190 --> 00:09:07,460 So for us now, then we are going to evaluate this expression, not any greater than Beeton, which 112 00:09:07,460 --> 00:09:10,420 is true so far and true it used to. 113 00:09:10,430 --> 00:09:18,650 First, we got to take a logic that we can take the table and if any one of the expression becomes false, 114 00:09:18,650 --> 00:09:23,660 then and end the table will be false and then they will to be true. 115 00:09:24,260 --> 00:09:27,470 Both expression should be true to argue the false. 116 00:09:31,220 --> 00:09:33,500 So I need to put the brackets. 117 00:09:36,150 --> 00:09:36,960 Think so. 118 00:09:43,910 --> 00:09:48,650 So we have so we need to put the hyphen here. 119 00:09:48,810 --> 00:09:51,140 I just forgot this one. 120 00:09:51,170 --> 00:10:02,280 So now let's execute this one because it is and see the first let's start our derby. 121 00:10:03,230 --> 00:10:05,240 Now, let me explain what happened here. 122 00:10:05,290 --> 00:10:08,810 Dorottya is 30 and 20, not as equals two. 123 00:10:09,290 --> 00:10:10,400 So they're not equal. 124 00:10:10,410 --> 00:10:10,770 Right. 125 00:10:11,030 --> 00:10:12,740 So we have got that for us. 126 00:10:13,040 --> 00:10:15,920 And greater than true, false and true. 127 00:10:15,920 --> 00:10:16,780 It is too far. 128 00:10:17,270 --> 00:10:22,070 She can see the two of there and get you get the for us. 129 00:10:23,150 --> 00:10:23,970 And that's it. 130 00:10:24,030 --> 00:10:24,740 These are. 131 00:10:30,030 --> 00:10:38,150 So are get really hard, it will only be followed whenever both executions are on the left and the right 132 00:10:38,150 --> 00:10:38,470 answer. 133 00:10:38,730 --> 00:10:42,150 If any of the expression is true, the whole expression will be true. 134 00:10:43,170 --> 00:10:47,580 So you can see the truth here and you can also say not. 135 00:10:52,780 --> 00:11:04,930 And it's excuse you, oh, sorry, I think we cannot compare the Norwegians, uh, Religare, and then 136 00:11:04,930 --> 00:11:08,320 we can apply a whole lot to this expression. 137 00:11:15,120 --> 00:11:23,760 All right, OK, so first, I think it's not not happening only to this refinancing, so let's put the 138 00:11:23,760 --> 00:11:26,830 brackets, think it will work. 139 00:11:28,410 --> 00:11:34,500 So as you can see, no, not has been applied to your expression, so you need to separate them with 140 00:11:34,500 --> 00:11:35,220 the brackets. 141 00:11:35,580 --> 00:11:36,970 So that's all for this video. 142 00:11:36,990 --> 00:11:43,410 I hope you have understood these operators and these are very helpful for checking the conditions and 143 00:11:43,410 --> 00:11:46,980 looping over the, uh, in the for loops, etc.. 144 00:11:46,980 --> 00:11:47,180 So.
