Multiplication of Three Digit Numbers (3 x 3 Digits)

Hi Kids,
Here, let us see how to multiply 2 three digit numbers. For example, let us consider the numbers 228 and 121.

228x121image

Write the numbers one below the other, as given in the below image.

Multiplication

As we did in the previous multiplication problems, we need to first multiply 1 of 121 with 228, in this math. Let us do that one at a time.
Multiply the “ones” first. Multiplying 8 with 1, we get 8. Write 8 in the answer “ones” column.

Multiplication

Next, multiplying 1 with 2, we get 2. Write 2 in the “tens” column.

Multiplication

Now multiplying 1 with 2, we get 2. Write 2 in the “hundreds” column.

Multiplication

As done in the previous multiplication problems, let us multiply 2 of three digit number 121 with 228. Write 0 below 8 in the answer column.
Multiplying 2 and 8, we get 16. Write 6 in the answer column and carry over 1 to the “tens” column.

Multiplication

Multiply 2 with 2 of 228. We get 4. Add the carry over 1 with 4. We get 5. Write 5 in the answer column.

Multiplication

Again multiplying 2 and 2, we get 4. Write it in the answer column. We get 4560.

Multiplication

Now we have 1 remaining in 121 to be multiplied with 228. Since 1 is the third digit of the three digit number 121, we need to write 0 in both “ones” and “tens” place of the answer column. Multiplying 1 and 8, we get 8 in this multiplication problem. Write it below 5 in the answer column.

Multiplication

Multiplying 1 and 2, we get 2. Write 2 in the answer column.

Multiplication

Again multiplying 1 and 2, we get 2. Write 2 in the answer column.

Multiplication

Now add the digits in order, from “ones” column.

Multiplication

Thus we get the answer 27588 by multiplying 228 and 121. Follow the above steps for similar problems to understand the concept better.
