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. ```  6  29  67   3 ``` 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. ```   6   29   67  203 ``` 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  174 ``` A line is drawn under the lower product (174) and the products are added together to get the final answer of 1943. ```    5    29    67   203  174  1943 ``` Return to Top
