Step-by-Step Guide

  1. Step 1: Write the two digit numbers next to each other as so: 97 x 93 Note: This example is for two-digit numbers that start with the same number and have second digits that equal 10 when added together (in this example

    In this case that would be: 7 x 3 = 21 , Here you can see that the final answer will look like xx21 ,,, 9021 , Keep in mind that the first digits are the same and the sum of the second digits equals
    10. 98 x 92 , 98 is
    -2 from 100, so write
    -2 above 98 92 is
    -8 from 100, so write
    -8 above 92 , You will see that it results in the same number. 98
    - 8 = 90 92
    - 2 = 90 ,,
    -2 x
    -8 = 16 , 9016 ,, 104 is +4 from 100, so write +4 above 104 103 is +3 from 100, so write +3 above 103 , You will see that it results in the same number. 104 + 3 = 107 103 + 4 = 107 ,, 4 x 3 = 12 , 10712
  2. Step 2: both numbers start with 9 and the second digits

  3. Step 3: 7 and 3

  4. Step 4: have a sum of 10).

  5. Step 5: we multiply the two second digits together.

  6. Step 6: Place this result to the right-hand side of the final answer.

  7. Step 7: Now add 1 to the first digit of the first number: 9 + 1 = 10

  8. Step 8: Multiply 10 by the first digit of the second number: 10 x 9 = 90

  9. Step 9: Place this result on the left-hand side of the final answer

  10. Step 10: and you'll see that you have quickly calculated the correct answer to the original problem.

  11. Step 11: Take another set of two-digit numbers to be multiplied.

  12. Step 12: Above each number

  13. Step 13: right the difference

  14. Step 14: or how deficient each of the numbers is from 100.

  15. Step 15: Cross-subtract these numbers from the value on the other side of the multiplication sign.

  16. Step 16: Place this number to the left-hand side of the final answer Now you can see that the final answer will look like 90xx

  17. Step 17: Multiply the two differences together.

  18. Step 18: Place this number to the right-hand side of the final answer

  19. Step 19: and again see that you have quickly calculated the correct answer to the original problem.

  20. Step 20: Take the two three-digit numbers to be multiplied and write as so: 104 x 103

  21. Step 21: Now that we are above 100

  22. Step 22: right down how much higher each number is from 100.

  23. Step 23: Cross-add these numbers from the value on the other side of the multiplication sign.

  24. Step 24: Place this number to the left-hand side of the final answer Now you can see that the final answer will look like 107xx

  25. Step 25: Multiply the two differences together.

  26. Step 26: Place this number to the right-hand side of the final answer

  27. Step 27: and even here you'll be able see that you have quickly calculated the correct answer.

In this case that would be: 7 x 3 = 21 , Here you can see that the final answer will look like xx21 ,,, 9021 , Keep in mind that the first digits are the same and the sum of the second digits equals
10. 98 x 92 , 98 is
-2 from 100, so write
-2 above 98 92 is
-8 from 100, so write
-8 above 92 , You will see that it results in the same number. 98
- 8 = 90 92
- 2 = 90 ,,
-2 x
-8 = 16 , 9016 ,, 104 is +4 from 100, so write +4 above 104 103 is +3 from 100, so write +3 above 103 , You will see that it results in the same number. 104 + 3 = 107 103 + 4 = 107 ,, 4 x 3 = 12 , 10712
