Jojo is thinking.
Jojo, what are you thinking?
You know, I am going
to be the richest in the jungle.
When? How? I heard a
merchant say that one mango can be sold for 5 coins.
I have 12 mango trees
in my orchard and there are 25 mangoes on each tree.
So, how many coins
will you get then? I don’t know. Let’s find out.
To find out the number
of coins, we must first find out the number of mangoes.
There are 12 trees and
each tree has 25 mangoes.
So, the total number
of mangoes would be the product of 12 and 25.
Number of trees = 12
Number of mangoes on
each tree = 25
Total number of
mangoes = 12 x 25
Do you know how to
multiply? Yes! I do. But I can only multiply a number with one digit.
But here, we need to
multiply with a 2 digit number.
Ok, I will teach you.
Ok, I will teach you.
As you know we start
in the one places.
Step 1: Multiply by
ones. First multiply 5 by 2 we get 10. Put down 0 and carry 1.
Now, multiply the tens
of the top number with the one on the bottom number.
That is 5 multiply by
1 is equal to 5, add 1 to 5 we get 6.
We have finish multiplied the top number with the one of the bottom number.
The product of
multiply the first digit was placed on the first line.
The product of
multiply the second digit will go on the second line.
Step 2: Multiply by
tens.
The second number multiply is 2 which is in the tens place or 20, take 0 from the 20 and places on the second line.
The second number multiply is 2 which is in the tens place or 20, take 0 from the 20 and places on the second line.
Now, multiply by 2. 2
multiply by 2 is 4. Put down the 4.
Next, multiply 2 by 1
we get 2.
This is very important to keep your number in the strip line.
This is very important to keep your number in the strip line.
Step 3: Add.
Add the two products.
That is 60 plus 240 we get 300.
0 plus 0 is 0, 6 plus 4 is 10, put down the 0, caring the 1.
Add the two products.
That is 60 plus 240 we get 300.
0 plus 0 is 0, 6 plus 4 is 10, put down the 0, caring the 1.
Now, add 1 plus 2, and
we get 3.
So 12 multiply by 25 is equals to 300.
So 12 multiply by 25 is equals to 300.
You have a total of
300 mangoes. And one mango can be sold for 5 coins.
So, Jojo will get 300
multiply by 5 coins.
Jojo, can you multiply 300 by 5?
Jojo, can you multiply 300 by 5?
Yes, it’s 1500 coins.
Wow! You would be so rich. But what will you do with all that money?
