Multiplying two digit by one digit numbers
How to multiply a two digit number by a one digit number
(for example 43 * 2).
- Place one number above the other so that the ones'
place digits are lined up. Draw a line under the bottom number.
- Multiply the ones' place digits (3 * 2 = 6). Place the six below the
line in the ones' place column.
- Multiply the digit in the tens' place column (4) by the digit in the ones'
place of the second number (2). The result is 4 * 2 = 8. Place the answer below
the line and to the left of the 6.
