| 00:0-1 | Welcome to the Tech Math channel . What I'm gonna | |
| 00:02 | be looking at in today's video is just basic short | |
| 00:04 | division . Okay , how we go about doing this | |
| 00:07 | , There's no little tricks for this is just pretty | |
| 00:09 | much straight forward what you do . So pretend you | |
| 00:12 | got the question here . I ask you what is | |
| 00:15 | 108 divided by three ? Who ? A bit of | |
| 00:22 | a nasty question ? Well , first off , generally | |
| 00:25 | what we do is we write these a little bit | |
| 00:27 | differently when we start to get bigger numbers than we | |
| 00:29 | do this , right , 100 and eight in here | |
| 00:33 | . The thing is being divided up , we put | |
| 00:34 | inside this little half box and then we put the | |
| 00:37 | thing , we're dividing it by over here and we | |
| 00:40 | start , well , we start on this end and | |
| 00:43 | we start dividing the numbers into each number as we | |
| 00:47 | go . So what's one divided by three ? Well | |
| 00:49 | , one is bigger than three . You can't do | |
| 00:51 | this . So what we do is we Put a | |
| 00:53 | zero there And we can carry the one from the | |
| 00:57 | 10 across . What is 10 divided by three ? | |
| 01:03 | Well , 10 divided by three is 3 three times | |
| 01:07 | three . Who's nine ? All right . How much | |
| 01:14 | Left over from 10 ? If you if you take | |
| 01:16 | nine away , how much is left over content or | |
| 01:18 | the answer is one . So we move this one | |
| 01:20 | across to the next part of the question And this | |
| 01:23 | leads us . Now you read this as 18 ? | |
| 01:26 | Yeah , 18 divided by three . The answer is | |
| 01:31 | six . So answer . It's 36 . I'll give | |
| 01:37 | you another one of these . Yeah . All right | |
| 01:43 | . What about this one here ? We will do | |
| 01:46 | but We'll do 612 divided for six . What does | |
| 01:55 | that equal ? Okay , so again , uh we | |
| 01:59 | make this thing here and We put the 612 in | |
| 02:03 | here . We put the six here and we start | |
| 02:07 | dividing With this number here . So six divided by | |
| 02:10 | six is one . one divided by six . Well | |
| 02:16 | , One divided by six . You can't do because | |
| 02:18 | one's smaller than six . So you get this one | |
| 02:21 | and you carried across To the next number and equal | |
| 02:25 | zero up here . Sure . It can't be done | |
| 02:28 | . Okay . This is a really important thing to | |
| 02:30 | get A lot of people don't put the zero in | |
| 02:31 | here uh and get the wrong answer . Therefore , | |
| 02:34 | okay , because you can't do it doesn't mean you | |
| 02:36 | just straight away carry the number . Of course you | |
| 02:38 | have to put this here and there . And then | |
| 02:40 | this number now we we read is 12-12 divided by | |
| 02:43 | six . Is to Okay , one more ? Yeah | |
| 02:51 | . Where are we ? Okay . What about this | |
| 02:55 | one ? Here we go . 545 . And we'll | |
| 03:01 | divide that by fourth . Again we put inside this | |
| 03:08 | box here . 545 divided by five . Yeah , | |
| 03:15 | Let's start working in this Division five divided by five | |
| 03:18 | is 1 . four divided by five . You can't | |
| 03:21 | do . So we have to put the zero up | |
| 03:23 | there and we carry this four across 45 , divided | |
| 03:28 | by five is nine . All right . I'll tell | |
| 03:33 | you what , I'll put a bunch of these up | |
| 03:35 | . I'll put them up in this type of format | |
| 03:37 | and I'll get you to solve them . See , | |
| 03:39 | here you go . Okay , so here's some questions | |
| 03:42 | here . See here you go with them . I'm | |
| 03:45 | going to come back and count of five . You | |
| 03:47 | might want to pause me and I'll come back and | |
| 03:50 | go through the answers . So 12 three , two | |
| 03:56 | thought , All right , here's the first answer here | |
| 03:59 | . six divided by three is too nine divided by | |
| 04:03 | three is 3 . Three divided by three is 1 | |
| 04:09 | , is our answer . I hope you do well | |
| 04:10 | on that . The next 11 divided by four . | |
| 04:14 | We can't do . So I carry the one across | |
| 04:17 | 12 divided by 4th is three one divided by four | |
| 04:22 | . We can't do Put the zero up there and | |
| 04:24 | I carry the one across 16 divided by four . | |
| 04:28 | It's full . So , you know , two , | |
| 04:31 | How are you doing ? Really , really well . | |
| 04:32 | So I thought four divided by five . We can't | |
| 04:37 | do So we carry the four across zero up there | |
| 04:41 | as well . 48 divided by five . Well 9545 | |
| 04:48 | and we need there's three left over . So I | |
| 04:50 | put the three there And then 35 divided by five | |
| 04:56 | is seven . So and through seven Last of all | |
| 05:01 | , eight divided by six is 1 . There's two | |
| 05:04 | leftovers to carry it . Next we have is 21 | |
| 05:08 | divided by 63 sixes 18 So there's a three and | |
| 05:13 | 1819 , left over in 36 . 6 , 6 | |
| 05:20 | is So here it is 136 . How did you | |
| 05:25 | go with those ? I hope you did really , | |
| 05:27 | really well . If you have any questions , please | |
| 05:29 | don't hesitate to send me a message . Okay , | |
| 05:33 | See you next time . |
