Find the product of 47 x 14.

Step: 1

First, place the multiplicand 47 on top and write the multiplier 14 below it.

Next, multiply the ones digit of the multiplier, 7, with the multiplicand 47. This will give you 47 × 4 = 188. Write this as the first partial product on a new line.

$1a$

Explanation:

In this step, we’ll multiply 47 by 4. First, multiply 4 by 7 to get 28. Place 8 in the one’s place and carry 2 to the tens column. Next, multiply 4 by 4 to get 16. Add 16 to the carried-over 2 to get 18. Therefore, the answer is 188, 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 47 × 1 = 47. Finally, we get 470.

$2a$

Explanation:

In this step, multiply the bottom tens digit, 1, by the number on the top, 7. So, 7 x 1 = 7. Write down the number 0 next to the 0. For 4 x 1 = 4, write 4 next to the 7 you already wrote down. This way, you will get the final answer of 470. This is the second partial product placed in another line.

Step: 3

Add both partial products to get the final product This will be 188 + 470 =658.

$3a$

Explanation:

Add both of your results to get a final answer. Now need to add 188 + 470 to get 658.
