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:

Find the product of 16 x 8.

Step: 1a

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 16 on top and multiplier 8 on bottom.

Step: 1b

Multiply the digit in the one’s place, which is 8 in this case, with the multiplicand 6. This will give 6 × 8=48.

$1b$

Explanation: In this step, multiply 6 by 8, to get 48. Place the 8 in one’s column and carry over the 4 to the preceding in ten’s column.

Step: 1c

Multiplying with the ten’s column digit 1 by 8. This will give 1 × 8 =8.

$1c$

Explanation: In this step, multiply the top ten’s digit, which is 1 by the bottom one digit 8. This will give 1 × 8 =8. Add 8 to the carry-over number 4, (8 + 4=12). We get the answer is 12. Write down the number 12 next to the 8. This way we get the final answer 128.

Step: 1d

The result obtained after multiplication is 16 × 8 =128.

$1d$

Explanation: Thus, the answer is 128, obtained by multiplying 16 with 8.
