### Multiply 3-Digit by 1-Digit Numbers: Learn

How to multiply a three-digit number by a one-digit number (for example 159 * 7).
• Place one number above the other so that the ones' place digits are lined up. Draw a line under the bottom number.  1 5 9 * 7
• Multiply the two ones' place digits (9 * 7 = 63). This number is larger than 9, so place the six above the tens' place column and place the three below the line in the ones' place column.  6 5 9 * 7 3
• Multiply the digit in the tens' place column (5) by the other number (7). The result is 5 * 7 = 35. Add the 6 to the 35 which equals 41. Place the one from the number 41 below the line and to the left of the other number. Place the 4 above the hundreds' place column.  4 6 5 9 * 7 1 3
• Multiply the digit in the hundreds' place column (1) by the digit in the ones' place of the second number (7). The result is 1 * 7 = 7. Add the 4 to the 7 (4 + 7 = 11). Place this below the line and to the left of the other digits.  4 6 5 9 * 7 1 1 1 3
