1 00:00:00,510 --> 00:00:03,230 Hello and welcome to this video. 2 00:00:03,420 --> 00:00:12,900 In this video harby Explaining what her arithmetic operators are and also showing you basic examples 3 00:00:13,650 --> 00:00:19,690 arithmetic operators are operators that I used to perform. 4 00:00:19,890 --> 00:00:26,430 Men take actions or functions on numbers or variables. 5 00:00:26,430 --> 00:00:32,220 Here's a table of some basic arithmetic operators. 6 00:00:32,250 --> 00:00:37,720 So start from the top where we've got the addition operator. 7 00:00:38,340 --> 00:00:43,660 Basically that is used to add numbers of values together. 8 00:00:43,860 --> 00:00:52,410 For example two plus two we've got the suppression operator which is used to surprise at numbers of 9 00:00:52,610 --> 00:00:53,720 values. 10 00:00:53,790 --> 00:00:58,360 Example for some pracht to Mex. 11 00:00:58,380 --> 00:01:06,780 We've got the multiplication operator which is basically used to multiply numbers or values. 12 00:01:06,840 --> 00:01:18,320 Example 7 times 3 in programming and in Javascript multiplication is represented by the asterisks symbol. 13 00:01:18,340 --> 00:01:24,720 Next we've got the division which is used to divide numbers or values. 14 00:01:24,720 --> 00:01:27,900 Example would divide 4 by. 15 00:01:27,960 --> 00:01:38,160 It makes we've got the S which is represented by the percent sign their model models operate or is used 16 00:01:38,160 --> 00:01:46,620 to return the remainder from the deficients and when the vital numbers mother laws will return only 17 00:01:46,890 --> 00:01:49,210 what is left from the division. 18 00:01:49,590 --> 00:01:57,240 Next we've got the increment operator which is represented by two plus symbols. 19 00:01:57,240 --> 00:02:02,940 What that does it increases the value of N number or is variable. 20 00:02:02,940 --> 00:02:10,140 For example if you've got a variable that has a value of 7 you want to increase their value to 8. 21 00:02:10,280 --> 00:02:17,700 He use the call the variable name and then you add B plus plus symbol which is the increment operator 22 00:02:18,030 --> 00:02:20,490 and that will increase the value bound 1. 23 00:02:20,840 --> 00:02:28,550 The positive that is the discriminant operator which is used to decrease the value of N number or a 24 00:02:28,650 --> 00:02:30,850 variable by Y. 25 00:02:30,900 --> 00:02:37,020 So these are the basic arithmetic operators in javascript. 26 00:02:37,020 --> 00:02:43,040 You also find that these are identical to most programming languages as well. 27 00:02:43,110 --> 00:02:49,860 So I'm going to go out to my console and basically show you some basic examples. 28 00:02:49,860 --> 00:02:56,840 Open on Google home page on the Google home page to access the console. 29 00:02:57,060 --> 00:03:03,750 If you are on a Windows computer you press control shift and J. 30 00:03:04,100 --> 00:03:08,540 If you are on a Mac you press command shift and J. 31 00:03:08,790 --> 00:03:11,540 That will give you access to the console. 32 00:03:11,760 --> 00:03:14,350 So I've got my console open. 33 00:03:14,370 --> 00:03:19,000 You should have this on the line next to the word console. 34 00:03:19,140 --> 00:03:25,050 So let me just run through the basic arithmetic operator but first I want to illustrate. 35 00:03:25,070 --> 00:03:29,170 If a basic addition you me already know this already. 36 00:03:29,190 --> 00:03:32,820 Would love apologize if I am going through this again. 37 00:03:33,000 --> 00:03:36,760 So I'm just going to illustrate by adding two numbers together. 38 00:03:37,150 --> 00:03:45,020 I'm going to do two plus two and press enter and that will give you four. 39 00:03:45,050 --> 00:03:47,840 Next let me illustrate this suppression. 40 00:03:47,850 --> 00:03:49,700 I'm going to surprise two numbers. 41 00:03:49,740 --> 00:03:59,230 So for from to press and time my keyboard and that will return the value of two. 42 00:03:59,260 --> 00:04:10,800 Next I want to multiply two moves so I'll do a 7 and Asterix Asterix is what you use to represent multiplication 43 00:04:10,890 --> 00:04:20,240 in javascript and will multiply 7 by 3 Press pentair that returns 21. 44 00:04:20,260 --> 00:04:23,770 Next I'm going to illustrate a deficient example. 45 00:04:23,800 --> 00:04:34,440 I'm going to divide two numbers so I'd divide 8 by 4 and you represent division with the slash symbol 46 00:04:34,680 --> 00:04:38,110 press enter and that will return to. 47 00:04:38,460 --> 00:04:47,250 Next I want to illustrate the model lost operator more will only return the value of what is left after 48 00:04:47,430 --> 00:04:48,370 division. 49 00:04:48,600 --> 00:04:51,170 So I'll do fine. 50 00:04:51,870 --> 00:04:54,690 And the percent to a percent more deloss. 51 00:04:55,110 --> 00:04:59,800 So I expect this to return 1 because 2 can only go into. 52 00:05:00,090 --> 00:05:02,060 Twice and it should be. 53 00:05:02,100 --> 00:05:05,760 Remember one he can say is returned one next. 54 00:05:05,790 --> 00:05:09,870 I want to illustrate how the incremental operator works. 55 00:05:09,900 --> 00:05:13,010 First I'm going to declare a variable called X.. 56 00:05:13,370 --> 00:05:24,840 I'm going to give you the value of seven so that if I call that value variable x it will return seven. 57 00:05:24,990 --> 00:05:33,810 So if I want to change the value from 7 to 8 I can use the increment operator by just calling the variable 58 00:05:33,970 --> 00:05:43,130 basanti and doing plus plus twice and that will increase if I now call the variable base. 59 00:05:43,150 --> 00:05:52,160 Maybe I should now return a value off it makes I want to illustrate how the Discriminate operator works. 60 00:05:52,200 --> 00:06:04,190 First I'm going to declare a variable called Why I am going to give it a value or 5 next if I call that 61 00:06:04,200 --> 00:06:07,770 variable it will return to 5. 62 00:06:07,770 --> 00:06:10,990 So for example I want to decrease it to full. 63 00:06:11,350 --> 00:06:21,140 I'll just call the variable based name and use the decrements operator which is two dashes. 64 00:06:21,480 --> 00:06:22,530 Press Enter. 65 00:06:22,530 --> 00:06:24,840 Now if I call that variable y. 66 00:06:24,930 --> 00:06:27,100 Now show me a value or form. 67 00:06:27,360 --> 00:06:31,020 So that's basically how the Discriminate operator works. 68 00:06:31,020 --> 00:06:40,020 These are just very basic examples to illustrate how the javascript arithmetic operators work. 69 00:06:40,020 --> 00:06:41,190 Thanks for watching. 70 00:06:41,190 --> 00:06:42,250 Bye for now.
