00:00Hi kids! Today we will learn more on addition.
00:09Here are 10 stars on the board.
00:13And, if I paste 5 more, how many stars would be there in total?
00:23We can write it like...
00:27Write the bigger number first. That is 10.
00:341 is in the tens place.
00:380 is in the units place.
00:43Now, take the other number. That is 5.
00:505 is in ones place.
00:54So, write it below 0. Like this.
01:00Good!
01:03Now you have to add them.
01:07You will add them like...
01:100 and 5 are in ones place.
01:16So, add them first.
01:200 plus 5 and you get 5.
01:26So, write 5 below them.
01:31Good!
01:33Now, there is nothing to add in 1.
01:38So, write 1 as it is.
01:42So, we got to know 10 plus 5 equals 15.
01:52We have learnt how to write the numbers before adding them.
02:00Now, let's take another example.
02:05Here are 12 smileys on the board.
02:09And, if I paste 3 more smileys, how many smileys would be there in total?
02:18We can write it like...
02:22Write the bigger number first.
02:26That is 12.
02:291 is in the tens place.
02:342 is in the ones place.
02:38Now, take the other number.
02:42That is 3.
02:453 is in ones place.
02:49So, write it below 2.
02:52Good!
02:55Now you have to add them.
02:59You will add them like...
03:022 and 3 are in ones place.
03:06Add them first.
03:102 plus 3, we get 5.
03:15Write 5 below them.
03:19Now, there is nothing to add in 1.
03:24So, write 1 as it is.
03:28So, we got to know 12 plus 3 equals 15.
03:37So, there will be 15 smileys in total.
03:42Good!
03:45Now, let's take another example.
03:50Here are 16 moons on the board.
03:55And, if I paste 12 more moons, how many moons would be there in total?
04:04We can write it like...
04:07Write the bigger number first.
04:10That is 16.
04:131 is in the tens place.
04:176 is in the ones place.
04:22Now, take the other number.
04:26That is 12.
04:292 is in ones place.
04:32So, write it below 6.
04:351 is in tens place.
04:40So, write it below 1.
04:43Good!
04:46Now, you have to add them.
04:49You will add them like...
04:526 and 2 are in ones place.
04:57Add them first.
05:006 plus 2, we get 8.
05:05So, write 8 below them.
05:09Now, add the digits in tens place.
05:15That is 1 plus 1, we get 2.
05:22And, write the sum below tens place.
05:27So, we got to know 16 plus 12 makes 28.
05:36So, there will be 28 moons in total.
05:42Good!
05:44So, kids, now you know how to write the numbers before adding them.
05:51And, then how to add them.
05:54Now, you may go ahead and take a quiz to learn more.
05:58Bye-bye!
