Title: Multiplications

Grade: 3-a Lesson: S1-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 19 x 3

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 19 on top and multiplier 3 on bottom.

Step: 1b

Multiply the digit in the one’s place, which is 3 in this case, with the multiplicand 9. This will give 9 × 3=27.

$1b$

Explanation: In this step, multiply 9 by 3, to get 27. Place the 7 in one’s column and carry over the 2 to the preceding in ten’s column.

Step: 1c

Multiplying with the ten’s column digit 1 by 3. This will give 1 × 3 =3.

$1c$

Explanation: In this step, multiply the top ten’s digit, which is 1 by the bottom one digit 3. This will give 1 × 3 =3. Add 3 to the carry-over number 2, (3 + 2=5). We get the answer is 5. Write down the number 5 next to the 7. This way we get the final answer 57.

Step: 1d

The result obtained after multiplication is 19 × 3 =57.

$1d$

Explanation: Thus, the answer is 57, obtained by multiplying 19 with 3.
