Find the product of 60 x 25.

Step: 1

First, place the multiplicand 60 on top and write the multiplier 25 below it.

Next, multiply the ones digit of the multiplier, 5, with the multiplicand 60. This will give you 60 × 5 = 300. Write this as the first partial product on a new line.

$1a$

Explanation:

In this step, we’ll multiply 60 by 5. First, multiply 0 by 5 to get 0. Place 0 in the one’s place. Next, multiply 6 by 5 to get 30. Therefore, the answer is 300, the first partial product placed in one line.

Step: 2

Write 0 in the one’s column. Multiply 2 by the multiplicand. This will give 60 × 2 = 120. Finally, we get 1200.

$2a$

Explanation:

In this step, multiply the bottom tens digit, 2, by the number on the top, 0. So, 2 x 0 = 0. Write 0 in the tens place. For 6 x 2 = 12, write 12 next to the 0 you already wrote down. This will give you the final answer of 1200. This is the second partial product placed on another line.

Step: 3

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

$3a$

Explanation:

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