**Math Story : 2 – Digit Multiplication**

**The Books In The Library**

**The Books In The Library****Narrator :** Triho and Cirha like reading. They often visit Samper town’s library which is managed by Uncle Math’s friend Madam, Word.

**Cirha and Triho :** Hello, Madam Word.

**Madam Word : **Hello, children, I am glad to see you here. I need to go for some urgent work and need your help to take care of the library today.

**Cirha :** Sure, Madam Word.

[Suddenly they hear a weird noise.]

**Triho : **Who could it be?

[They rush to find out.]

**Cirha :** Oh no! Atrihos are attacking the library.

**Atrihos : **We want these best mathematics books to help our boss design deadly gadgets. Samper town will be over.

**Cirha : **No! We cannot let Atrihos take the books from library.

**Triho :** I know how to deal with them.

[Cirha and Triho fight the Atrihos bravely.]

**Atrihos :** Argh! This time, you saved the library but we will come back stronger!

**Cirha : **Pheww! They are gone. Such a relief! But let us quickly check if we have all the books or not? I think we should ask for help from Uncle Math.

**Uncle Math : **I am here already. Mr Messenger informed me about the attack.

**Cirha** **: **There are 12 bookshelves and each shelf has 15 books. We are totally confused, Uncle Math. Please help us find the total number of books.

**Uncle Math :** Multiplying 12 and 15 will give us the count of total books.

**Cirha :** But how? We only know how to multiply single-digit numbers.

**Uncle Math :** No fear! When I am here. [says Uncle Math and grabs a board.]

**Uncle Math : **Whenever we multiply two-digit numbers, there are certain steps that we follow. Let us learn the steps one by one.

Step 1 : Arrange the given numbers in the column according to their place value.

Step 2 : Now, we will first multiply the digit in ones place of the number at the bottom, with all the digits of the number at the top. So, on multiplying 5 by 12 we get 60.

Step 3 : Then, put zero as a place holder and multiply the tens digit of the bottom number by all the digits of the number at the top. On multiplying 1 by 12, along with the placeholder, we get 120.

Step 4 : Finally, adding both products will give us the final product.

**Triho :** So, by adding 60 and 120, we get 180.

**Uncle Math :** Absolutely correct!

[Cirha quickly counts if there were all 180 books.]

**Triho : **Woohoo! Atrihos could not take even a single book from the library. This is a relief.

**Uncle Math : **Thanks a lot, Cirha and Triho. Because of your bravery, we could save the town again.
