| 00:00 | you know , and welcome to the Tech Math channel | |
| 00:02 | . What we're going to be having all that today | |
| 00:04 | is going to look at that . How to add | |
| 00:06 | two numbers together to large numbers together . So Pretend | |
| 00:10 | We're going to add the numbers together . 1074 Plus | |
| 00:19 | 627 Okay . How do we go about doing this | |
| 00:23 | ? Well , the first thing what you have to | |
| 00:26 | do is you have to , when you're doing these | |
| 00:28 | stuff standard ways you want to actually um write the | |
| 00:31 | numbers down . So one number Is on the line | |
| 00:35 | above the other numbers , you start listening of one | |
| 00:39 | above the other . So 1074 and 627 . Now | |
| 00:46 | , what you're going to notice is that units lined | |
| 00:47 | up with units , the tens , line up with | |
| 00:49 | the tens , hundreds lined up with the hundreds and | |
| 00:52 | there's a thousands there . Okay , So we put | |
| 00:55 | the line underneath there and we're gonna start adding these | |
| 00:58 | together . So we're going to start on the right | |
| 01:02 | hand side . Yeah , 4-plus 7 . The answer | |
| 01:06 | to that is 11 . Now , instead of writing | |
| 01:08 | the 11 down , we don't write every single number | |
| 01:10 | down here , we only write down the units number | |
| 01:13 | , So four plus seven Is 11 . So what | |
| 01:16 | do we do with that tens number that we get | |
| 01:17 | here ? We carry it across to the next column | |
| 01:21 | here , Okay . Because it was 11 . It | |
| 01:24 | was a tens , we could have one there . | |
| 01:26 | Okay . And now we counted here , so one | |
| 01:29 | plus seven is eight plus two , 10 . So | |
| 01:34 | 10 the units is zero And there's A10s number which | |
| 01:38 | would carry across to the next column . One plus | |
| 01:42 | nothing is one plus six is seven . And then | |
| 01:47 | last of all with thousands one . Well , it's | |
| 01:52 | not adding to anything , so the answer is 1,701 | |
| 01:58 | . Okay , pretty easy . Right , I'll give | |
| 02:00 | you another one to go . All right , let's | |
| 02:06 | go something else here . Let's write the question down | |
| 02:10 | . Uh 2850 for plus 792 . Okay , So | |
| 02:20 | first off we write them In that particular way that | |
| 02:23 | we wrote them before . So the units are going | |
| 02:24 | to line up with the units attends are going to | |
| 02:26 | line up with the 10s and hundreds are going to | |
| 02:28 | line up in the hundreds . Okay , so 2854 | |
| 02:35 | Plus 792 . Okay , put these and two lines | |
| 02:44 | here and here we go For a start on this | |
| 02:49 | right hand side again . four plus 2 . It's | |
| 02:52 | six , 5-plus 9 is 14 . So we put | |
| 02:57 | the units the four down there and we carry the | |
| 02:59 | one across one plus 8 is nine plus seven is | |
| 03:04 | 16 . We put in six there , we carry | |
| 03:08 | the one across one plus two . His strength . | |
| 03:13 | The answer is 3646 . I hope you get these | |
| 03:19 | . They're really , really a very , very basic | |
| 03:21 | part of mats . But really , really important to | |
| 03:23 | get . What I recommend is probably what you want | |
| 03:25 | to be able to do is you want to start | |
| 03:27 | getting that work out . But if you find a | |
| 03:30 | say , listen , I know how to do that | |
| 03:31 | already . I find that really really quite okay to | |
| 03:34 | do with what I'd recommend is you start trying to | |
| 03:36 | go to this next method , which I'll put a | |
| 03:38 | link up . Now how you would actually go about | |
| 03:40 | trying to add these and instead of going from right | |
| 03:44 | to left arm , adding going from left to right | |
| 03:46 | , because this starts enabling you to actually work things | |
| 03:48 | out and you had a whole lot more . Okay | |
| 03:51 | , Okay , so give that a go links up | |
| 03:53 | there , we'll see you next time . |
