Title: Multiplications

Grade: 2-a Lesson: S4-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

Multiply 8 x 22

Write the largest number or the multiplicand on the top side and one digit number or the multiplier on the bottom.

$1a$

Explanation: Arrange the numbers vertically.

Step: 1b

Start by multiplying the digit in the one’s place of the bottom number by the digit in the one’s place of the top number,i.e., \$8 \times 2 = 16\$.
Write down 6 and carry over 1 to the tens place.

$1b$

Explanation: Start by multiplying the ones place, i.e., 8 x 2 = 16. Then carry over 1 to the preceding ten’s column and write 6 below the one’s column.

Step: 1c

Now, multiply the number in the tens place by 6,i.e.,8 × 2 = 16 tens.
Finally, add 1(carry over) + 16= 17. Write 17 at the tens place.
Therefore, 8 x 22 = 176.

$1c$

Explanation: In this step, multiply the digit at the tens place by 8. 8 × 2 = 16 tens.Now, 16 + 1(carry over) = 17 tens. Hence, 8 x 22 = 176.
