Title: Multiplications

Grade: 3-a Lesson: S3-L8

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 50 & 10.

Arrange the numbers 50 and 10 in columns according to their places.
Multiply 0 by each digit of 50:
Start by multiplying 0 by 0, which gives us 0 (0 x 0 = 0). We write 0 in the one’s column.
Then, we multiply 0 by 5 (0 x 5 = 0) and write 0 in the tens place.
Thus, our final answer is 00.

$1a$

Explanation: In this step, arrange 50 and 50 in columns according to their places. Multiply 0 by each digit of 50, 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 1 multiplied by each digit of 50, follow these steps.
Multiplying 1 by 0, which gives us 0 (1 x 0 = 0). Write 0 in the one’s column.
Then, multiply 1 by 5 (1 x 5 = 5) and write 5 in the tens place.
Thus, our final answer is 500.

$1c$

Explanation: In this step, To find the product of 1 multiplied by each digit of 50, follow these steps: Multiply 1 by 0 to get 0. Multiply 1 by 5 to get 5. Write 5 in the hundreds column. The final answer is 500.

Step: 1d

Add both partial products to get the final product
This means 00 + 500 = 500.
Therefore, the final product is 500.

$1d$

Explanation: Add both results to get a final answer. Now, we need to add 00 + 500 to get 500.
