Title: Multiplications

Grade: 3-a Lesson: S3-L2

Explanation: The best way to understand multiplications is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Step: 1a

Find the product of 33 & 30.

Arrange the numbers 33 and 30 in columns according to their places.
Multiply 0 by each digit of 33:
Start by multiplying 0 by 3, which gives us 0 (3 x 0 = 0). We write 0 in the one’s column.
Then, we multiply 0 by 3 (3 x 3 = 0) and write 0 in the tens place.
Thus, our final answer is 00.

$1a$

Explanation: In this step, arrange 33 and 30 in columns according to their places. Multiply 0 by each digit of 30, we get 00 as the answer.

Step: 1b

Now, we will place a zero (0) under the first partial product, that is, before writing the second partial product in the next line

$1b$

Explanation: In this step, before writing the second partial product in the next line, we will place a zero(0) under the first partial product.

Step: 1c

To find the product of 3 multiplied by each digit of 33, follow these steps.
Multiplying 3 by 3 gives us 9 (3 x 3 = 9). Write 9 in the tens column.
Next, multiply 3 by 3, give us 9 (3 x 3 = 9). Write 9 in the hundreds column.
Our final answer is 990.

$1c$

Explanation: To find the product of 3 multiplied by each digit of 33, multiply 3 by 3 to get 9. Write 9 in the tens column. Multiply 3 by 3 to get 9. Write 9 in the hundreds column to get the final answer: 990.

Step: 1d

Add both partial products to get the final product This means 00 + 990 = 990. Therefore, the final product is 990.

$1d$

Explanation: Add both results to get a final answer. Now, we need to add 00 + 990 to get 990.
