Multiplying two digit by one digit numbers

How to multiply a two digit number by a one digit number
(for example 59 + 7).

• Place one number above the other so that the ones' place digits are lined up. Draw a line under the bottom number.

 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.

• Multiply the digit in the tens' place column (5) by the second number (7). The result is 5 * 7 = 35. Add the 6 to the 35 (35 + 6 = 41) and place the answer below the line and to the left of the 3.
