Find the product of \$41 times 15\$.

Step: 1

First, place the multiplicand 41 on top, and write the multiplier 15 below it.

Next, multiply the ones digit of the multiplier, 5, with the multiplicand 41. This will give you 41 × 5 = 205. Write this as the first partial product on a new line.

$1a$

Explanation:

In this step, we’ll multiply 41 by 5. First, multiply 1 by 5 to get 5. Next, multiply 4 by 5 to get 20. Therefore, the answer is 205, the first partial product placed in one line.

Step: 2

Write a 0 in the one’s column. Multiply 1 by the multiplicand. This will give 41 × 1 = 41. Finally, we get 410.

$2a$

Explanation:

In this step, multiply the bottom tens digit, 1, by the number on the top, 1. So, 1 x 1 = 1. Write down the number 1 next to the 0. For 4 x 1 = 4, write down the number 4 next to the 1 that you already wrote down. This way, you will get the final answer of 410. This is the second partial product placed in another line.

Step: 3

Add both partial products to get the final product This will be 205 + 410 =615.

$3a$

Explanation:

Add both of your results to get a final answer. Now need to add 205 + 410 to get 615.
