Title: Multiplications

Grade: 2-a Lesson: S4-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

Multiply 3 x 14

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., \$3 \times 4 = 12\$.
Write down 2 and carry over 1 to the tens place.

$1b$

Explanation: Start by multiplying the ones place, i.e.,3 x 4 = 12. Then carry over 1 to the preceding ten’s column and write 2 below the one’s column.

Step: 1c

Now, multiply the number in the tens place by 3, i.e., 1 × 3 = 3 tens.
Finally, add 1(carry over) + 3= 4. Write 4 at the tens place.
Therefore, 3 x 14 = 42.

$1c$

Explanation: In this step,multiply the digit at the tens place by 3. 1 × 3 = 3 tens.Now, 3 + 1(carry over) = 4 tens. Hence, 3 x 14 = 42.
