Title: Multiplications

Grade: 3-a Lesson: S3-L4

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 38 & 11.

Arrange the numbers 38 and 11 in columns according to their places.
Multiply 1 by each digit of 38:
Start by multiplying 1 by 8, which gives us 8 (1 x 8 = 8). Write 8 in the one’s column.
Then, multiply 1 by 3 (1 x 3 = 3) and write 3 in the tens place.
Thus, our final answer is 38.

$1a$

Explanation: In this step, arrange 38 and 11 in columns according to their places. Multiply 1 by each digit of 38, we get 38 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 1 multiplied by each digit of 38, follow these steps.
Multiplying 1 by 8, which gives us 8 (1 x 8 = 8). Write 8 in the one’s column.
Then, multiply 1 by 3 (1 x 3 = 3) and write 3 in the tens place.
Thus, our final answer is 380.

$1c$

Explanation: In this step, To find the product of 1 multiplied by each digit of 38, follow these steps: Multiply 1 by 8 to get 8. Multiply 1 by 3 to get 3. Write 3 in the hundreds column. The final answer is 380.

Step: 1d

Add both partial products to get the final product
This means 38 + 380 = 418.
Therefore, the final product is 418.

$1d$

Explanation: Add both results to get a final answer. Now, we need to add 38 + 380 to get 418.
