Title: Multiplications

Grade: 4-a Lesson: S2-L8

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 60 x 25

Arrange the numbers in vertically.

$1a$

Explanation: Place the multiplicand 60 on top and multiplier 25 on bottom.

Step: 1b

Multiply the one’s digit on the top number by the one’s digit of the bottom number…Here the digits are 0 x 5=0..write the product in ones column..

$1b$

Explanation: When 0 is multiplied by 5, we get 0. Write the digit 0 in ones column.

Step: 1c

Multiply the tens digits on the top number by the ones digit of the bottom number…Here the digits are 6 x 5=30..write the product beside the ones column. since tens column

$1c$

Explanation: When 6 is multiplied by 5, we get 30. Write the digit 30 in the tens column. The first partial product is 300. That will be placed in one line.

Step: 1d

Multiply the one’s digits on the top number by the tens digit of the bottom number…Here the digits are 0 x 2=0..Place the value under the first partial product in the tens column.

$1d$

Explanation: When 0 is multiplied by 2, we get 0. Place the value under the first partial product in the tens column.

Step: 1e

Multiply the tens digits on the top number by the tens digit of the bottom number. Here the digits are 6 x 2=12. Write the value 12 under the hundreds column in the first partial product. Now the second partial product is 120.

$1e$

Explanation: When 6 is multiplied by 2, we get 12. Write the value 12 under the hundreds column in the first partial product. Here the second partial product is 120. which will be placed in another line. We have to put the 0 in the one’s column.

Step: 1f

Add the both first and second partial products 300 + 1200=1500

$1f$

Explanation: Add both of your results to get a final answer. Now need to add 300 + 1200 to get 1500.
