Find the product of 52 x 18.

Step: 1

First, place the multiplicand 52 on top and write the multiplier 18 below it.

Next, multiply the ones digit of the multiplier, 8, with the multiplicand 52. This will give, 52 × 8 = 416. Write this as the first partial product on a new line.

$1a$

Explanation:

In this step, we’ll multiply 52 by 8. First, multiply 8 by 2 to get 16. Place 6 in the one’s place and carry 1 to the tens column. Next, multiply 5 by 8 to get 40. Add 10 to the carried-over 1 to get 41. Therefore, the answer is 416, 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 52 × 1 = 52. Finally, we get 520.

$2a$

Explanation:

In this step, multiply the bottom tens digit, 1, by the number on the top, 1. So, 2 x 1 = 2. Write down the number 0 next to the 0. For 5 x 1 = 5, write 5 next to the 2 you already wrote down. This way, you will get the final answer of 520. This is the second partial product placed in another line.

Step: 3

Add both the first and second partial products 416 + 520=936.

$3a$

Explanation:

Add both of your results to get a final answer. Now need to add 416 + 520 to get 936.
