Multiplication of Two Digit Numbers
How to multiply a three digit number by a two digit number (e.g. 29 * 67).
 Place one number above the other so that the tens' and ones'
places are lined up. Draw a line under the bottom number.
29
67
 Multiply the two numbers in the ones' places. (9 * 7 = 63). This number is larger
than 9 so place a 6 above the tens' place column and place 3 below the
line in the ones' place column.
29
67
 Muliply the digit in the top tens' place column (2) by the digit in the lower ones'
place column (7). The answer (2*7=14) is added to the 6 above the top tens' place
column to give an answer of 20. The 20 is placed below the line to give 203 for
29 multiplied by 7.

 After 29 has been multiplied by 7 as shown above, 29 is multiplied by the tens'
place of the multiplier which is 6. The product of 29 times 6 is moved one place to the left because
we are multiplying by a tens' place number. The result would be 174:
5
29
67
203
 A line is drawn under the lower product (174) and the products are added
together to get the final answer of 1943.
