Title: Multiplications

Grade: 3-a Lesson: S2-L1

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 12 x 24

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 12 on top and multiplier 24 on bottom.

Step: 1b

Multiply the one’s digits on the top number by the one’s digit of the bottom number…Here, the digits are 2 x 4 = 8.write the product in one column.

$1b$

Explanation: In this step, when 2 is multiplied by 4, we get 8. Now, we write 8 in the one’s column.

Step: 1c

Multiply the tens digits on the top number by the ones digit of the bottom number.Here the digits are 1 x 4 = 4.

$1c$

Explanation: When 1 is multiplied by 4, we get 4. Write the digit 4 in tens column.

Step: 1d

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

$1d$

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: 1e

To find the product of 2 multiplied by each digit of 12, follow these steps:
Multiply 2 by 2 to get 4. Write 4 in the tens column.
Next, multiply 1 by 2 to get 2. Write 2 in the hundreds column.
The final answer is 240.

$1e$

Explanation: In this step, multiply 2 by each digit of 12: Multiply 2 by 2 to get 4, and write in the tens column. Multiply 1 by 2 to get 2, and write in the hundreds column. The final answer is 240.

Step: 1f

Add both partial products to get the final product
This means 48 + 240 = 288 .
Therefore, the final product is 288.

$1f$

Explanation: Add both results to get a final answer. Now, we need to add 48 + 240 to get 288.
