Find the product of 40 \$times\$ 24.

Step: 1

First, place the multiplicand 40 on top, and write the multiplier 24 below it.

Next, multiply the ones digit of the multiplier, 4, with the multiplicand 40. This will give you 40 × 4 = 160. Write this as the first partial product on a new line.

$1a$

Explanation:

In this step, we’ll multiply 40 by 4. First, multiply 0 by 4 to get 0. Next, multiply 4 by 4 to get 16. Therefore, the answer is 160, the first partial product placed in one line.

Step: 2

Write a 0 in the one’s column. Multiply 2 by the multiplicand. This will give 40 × 2 = 80. Finally, we get 800.

$2a$

Explanation:

In this step, multiply the bottom tens digit, 2, by the number on the top, 0. So, 0 x 2 = 0. Write down the number 0 next to the 0. For 4 x 2 = 8, write the number 8 next to the 0 you already wrote down. This way, you will get the final answer of 800. This is the second partial product placed in another line.

Step: 3

Add both partial products to get the final product This will be 160 + 800 =960.

$3a$

Explanation:

Add both of your results to get a final answer. Now need to add 160 + 800 to get 960.
