Title: Multiplications

Grade: 3-a Lesson: S1-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 17 x 2

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 17 on top and multiplier 2 on bottom.

Step: 1b

Multiply the digit in the one’s place, which is 2 in this case, with the multiplicand 7. This will give 7 × 2=14.

$1b$

Explanation: In this step, multiply 7 by 2, to get 14. Place the 4 in one’s column and carry over the 1 to the preceding in ten’s column.

Step: 1c

Multiplying with the ten’s column digit 1 by 2. This will give 1 × 2 =2.

$1c$

Explanation: "In this step, multiply the top ten’s digit, which is 1 by the bottom one digit 2. This will give 1 × 2 =2. Add 2 to the carry-over number 1, (2 + 1=3). We get the answer is 3. Write down the number 3 next to the 4. This way we get the final answer 34."

Step: 1d

The result obtained after multiplication is 17 × 2 =34.

$1d$

Explanation: Thus, the answer is 34, obtained by multiplying 17 with 2.
