Find the product of 19 x 3.

Step: 1

Arrange the numbers vertically.

Multiply the digit in the one’s place, 3 in this case, by the multiplicand 9. This will give 9 × 3 = 27.

$1a$

Explanation:

Place the multiplicand 19 on top and the multiplier 3 on the bottom. Next, multiply 19 by 3. Then, multiply 9 by 3, to get 27. Place the 7 in the ones column and carry over the 2 to the tens column.

Step: 2

Multiplying the digit 1 in the tens column by 3, i.e., 1 × 3 = 3. Add 3 to the carry-over number 2, i.e., 3 + 2 = 5, and write 5 in the tens column.

The result of 19 × 3 is 57.

$2a$

Explanation:

In this step, multiply the tens digit, 1, by the ones digit, 3. This will give us 1 × 3 = 3.Add 3 to the carry-over number 2 (3 + 2 = 5). The answer is 5. Write down the number 5 next to the 7. This way, we get the final answer, 57.
