00:00Hi kids, today we will be learning how we can use multiplication in our problems.
00:11So let's start!
00:15Can you calculate how many pencils are there in this picture?
00:205 sets are there and 10 pencils are there in each set.
00:30So we need to add 10 5 times.
00:35Remember we use multiplication for repeated addition problems.
00:43So instead of adding 10 5 times, we can multiply 10 with 5.
00:52So we get...
00:55So there are 50 pencils in the picture.
01:00Isn't it easier?
01:04Let's take one more example.
01:08Can you calculate how many eggs are there in this picture?
01:133 trays are there and each tray has 8 eggs.
01:21So we need to add 8 3 times.
01:28Remember we use multiplication for repeated addition problems.
01:34So instead of adding 8 3 times, we can multiply 8 with 3.
01:43So we get...
01:46So there are 24 eggs in the picture.
01:51Isn't it easier?
01:54So let's take one more example.
01:59There are 5 apples in one basket.
02:04Then 4 baskets will have how many apples?
02:09You need to add 5 4 times here.
02:14And you now know you can write repeated addition in the form of multiplication sentence.
02:23So 5 plus 5 plus 5 plus 5 can be written as 5 times 4.
02:36And we can easily solve it as 5 multiplied by 4 equals 20.
02:44So 20 apples will be there in 4 baskets.
02:51Let's move on to another question.
02:56One tray holds 6 cups, then 3 trays will hold how many cups?
03:04You need to add 6 3 times here.
03:09And you now know you can write repeated addition in the form of multiplication sentence.
03:19So adding 6 3 times can be written as 6 times 3.
03:27And 6 multiplied with 3 is 18.
03:33So 18 cups will be there in 3 trays.
03:40Let's move on to another question.
03:45One cat has 4 whiskers, then 3 cats will have how many whiskers?
03:54We need to add the number of whiskers here, so it's a problem of repeated addition.
04:024 plus 4 plus 4.
04:07And we now know repeated addition problems can be written as multiplication sentence.
04:16So we can write it as 4 multiplied with 3.
04:24And 4 times 3 equals 12.
04:29So 3 cats will have 12 whiskers.
04:35Now let's make one more multiplication sentence.
04:42One chair has 4 legs, then 8 chairs will have how many legs?
04:50Can you make the multiplication sentence for this problem?
04:55Let's see.
04:57We need to add the number of legs here, so it's a problem of repeated addition.
05:06Adding 4 8 times, so we can write it as 4 times 8.
05:15So our multiplication sentence will be 4 times 8 equals 32.
05:25So 8 chairs will have 32 legs.
05:31Good!
05:33So what have we learned?
05:36We have learned whenever there is a repeated addition problem, you can solve it using multiplication.
05:45Now you may go ahead and take a quiz to learn more.
05:49Bye-bye!
