Multiply 199 by 6.

Step: 1

Arrange the numbers vertically.
First, multiply the digit at the one’s place by 9, i.e., 9 x 6 = 54.
Write 4 in the ones column and carry over 5 to the tens column.

$1a$

Explanation:

In this step, multiply the digit in one’s place by 6. For instance, if the digit is 6, multiply it by 9, resulting in 54. Write down 4 in the ones column and carry over 5 to the tens column.

Step: 2

Next, multiply the digit in the tens place by 9: 9 × 6 = 54. Add the carry: 5 + 54 = 59.
Write down 9 in the tens column and carry over 5 to the hundreds column.

$2a$

Explanation:

In this step, 6 is multiplied by 9, resulting in 54. Add carry over 5 to 54, we get 59. Write 9 in the tens column and carry 5 to the hundreds column.

Step: 3

Now, multiply the digit in the hundreds’ place by 6, i.e., 1 × 6 = 6
Add carry 5 to 6, we get 11. Write 11 in the hundreds’ place.

Thus, the product of 199 and 6 is 1194.

$3a$

Explanation:

In this step, multiply the hundreds digit by 6: 1 x 6 = 6. Then, add 5 to 6 to get 11. Write 11 in the hundreds place, so 199 x 6 = 1194.
