Before going to this shortcut process we learned the multiplication of Two digit numbers and Three and Two digit numbers and we applied the shortcut process to obtain the result. Now we apply the same steps adding with new step.
 

Example #1 – Multiplication of Three Digit Numbers
548 x 456 = ?
The result of multiplication of three digit number is 548 x 456 = 249888.

Shortcut Tricks

  1. Multiply (6 x 8) = 48 (note down 8 carry 4).
  2. Then do cross multiplication( 5 x 8 + 6 x 4 + 4 (add carry)) = 68 (note down 8 carry 6).
  3. Again (6 x 5 + 5 x 4 + 4 x 8 + 6 (add carry)) = 88 (note down 8 carry 8).
  4. Again do cross multiplication and add carry (5 x 5 + 4 x 4 + 8) = 49 (note down 9 carry 4).
  5. Do multiplication of left numbers (4 x 5 + 4) = 24, note it down.
    And finally the result we get is 249888.

 

 

Example #2 – Multiplication of Three Digit Numbers
275 x 354 = ?
The result of multiplications of three digit number is 275 x 354 = 97350.

Shortcut Tricks

  1. Multiply (4 x 5) = 20 (note down 0 carry 2).
  2. Then do cross multiplication (5 x 5 + 4 x 7 + 2 (add carry)) = 55 (note down 5 carry 5).
  3. Again (4 x 2 + 3 x 5 + 5 x 7 + 5 (add carry)) = 63 (note down 3 carry 6).
  4. Again do cross multiplication and add carry (5 x 2 + 3 x 7 + 6) = 37 (note down 7 carry 3).
  5. Do multiplication of left numbers and add carry (3 x 2 + 3) = 9, note it down.
    And finally the result we get is 97350.

 

 

Example #3 – Multiplication of Three Digit Numbers
395 x 284 = ?
The result of multiplication of three digit number is 395 x 284 = 112180.

Shortcut Tricks

  1. Multiply (4 x 5) = 20 (note down 0 carry 2).
  2. Then do cross multiplication (4 x 9 + 8 x 5 + 2 (add carry)) = 78 (note down 8 carry 7).
  3. Again (4 x 3 + 2 x 5 + 8 x 9 + 7 (add carry)) = 101 (note down 1 carry 10).
  4. Again do cross multiplication and add carry (8 x 3 + 2 x 9 + 10) = 52 (note down 2 carry 5).
  5. Do multiplication of left numbers (2 x 3 + 5) = 11, note it down.
    And finally the result we get is 112180.

 

 

Example #4 – Multiplication of Three Digit Numbers
175 x 157 = ?
The result of multiplication of three digit number is 175 x 157 = 27475.

Shortcut Tricks

  1. Multiply (5 x 7) = 35 (note down 5 carry 3).
  2. Then do cross multiplication (7 x 7 + 5 x 5 + 3 (add carry)) = 77 (note down 7 carry 7).
  3. Again (1 x 7 + 1 x 5 + 7 x 5 + 7 (add carry)) = 54 (note down 4 carry 5).
  4. Do cross multiplication and add carry (1 x 5 + 1 x 7 + 5 (add carry)) = 17 (note down 7 carry 1).
  5. Again (1 x 1 + 1) = 2, note it down.
    And finally the result we get is 27475.

      then try this
      999 x 9 = 8991 add two zero to the left of number then
      999 x 9 = 8991 add one zero then
      999 x 9 = 8991 lastly add all you will get the ans 899100 + 89910 + 8991 = 998001

      U can solve 999X999 through this method. I have got the answer as follows:
      1) 9×9=81 , note down 1 & carry 8
      2)9×9+9×9=162+8=170, note 0 & carry 17
      3)9×9+9×9+9×9=243+17=260,note 0 & carry 26
      4) 9×9+9×9+26=188, note 8 & carry 18
      5) 9×9=81+18=99 note down 99
      Answer = 998001
