Title: Multiplications

Grade: 3-a Lesson: S1-L3

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 16 x 4

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 16 on top and multiplier 4 on bottom.

Step: 1b

Multiply the digit in the one’s place, which is 4 in this case, with the multiplicand 6. This will give 6 × 4=24.

$1b$

Explanation: In this step, multiply 6 by 4, to get 24. Place the 4 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 4. This will give 1 × 4 =4.

$1c$

Explanation: In this step, multiply the top ten’s digit, which is 1 by the bottom one digit 4. This will give 1 × 4 =4. Add 4 to the carry-over number 2, (4 + 2=6). We get the answer is 6. Write down the number 6 next to the 4. This way we get the final answer 64.

Step: 1d

The result obtained after multiplication is 16 × 4 =64.

$1d$

Explanation: Thus, the answer is 64, obtained by multiplying 16 with 4.
