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.
59
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.
