If you manage your time then you can do well in those exams. Most of us skip that part. We provide examples on Multiplication of Three digit numbers shortcut tricks here in this page below. We try to provide all types of shortcut tricks on multiplication of three digit numbers here. Visitors please read carefully all shortcut examples. These examples here will help you to better understand shortcut tricks on multiplication of three digit numbers.

Before starting anything just do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Using basic math formula do first ten maths of that page. You also need to keep track of timing. After solving all ten math questions write down total time taken by you to solve those questions. Now practice our shortcut tricks on multiplication of three digit numbers and read examples carefully. After doing this go back to the remaining ten questions and solve those using shortcut methods. Again keep track of timing. The timing will be surely improved this time. But this is not all you need. You need more practice to improve your timing more.
 
We all know that the most important thing in competitive exams is Mathematics. That doesn’t mean that other sections are not so important. But only math portion can leads you to a good score.

But it doesn’t mean that you can’t do math problems without using any shortcut tricks. You may do math problems within time without using any shortcut tricks. You may have that potential. But so many people can’t do this. So Multiplication of Three digit numbers shortcut tricks here for those people. Here in this page we try to put all types of shortcut tricks on Multiplication of Three digit numbers. But it possible we miss any. We appreciate if you share that with us. Your little help will help so many needy.
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 #1Multiplication of Three Digit Numbers
548 x 456 = ?
The result of multiplication of three digit number is 548 x 456 = 249888.
Step 1: Multiply ( 6 x 8) = 48 (note down 8 carry 4 ).
Step 2: Then do cross multiplication( 5 x 8 + 6 x 4 + 4 (add carry)) = 68 (note down 8 carry 6).
Step 3: Again (6 x 5 + 5 x 4 + 4 x 8 + 6 (add carry)) = 88 (note down 8 carry 8).
Step 4: Again do cross multiplication and add carry ( 5 x 5 + 4 x 4 + 8) = 49 (note down 9 carry 4).
Step 5: do multiplication of left numbers( 4 x 5 + 4) = 24, note it down.
And finally the result we get 249888.


Example #2 – Multiplication of Three Digit Numbers
275 x 354 = ?
The result of multiplications of three digit number is 275 x 354 = 97350.
Step 1: Multiply (4 x 5) = 20 (note down 0 carry 2).
Step 2: Then do cross multiplication (5 x 5 + 4 x 7 + 2 (add carry)) = 55 (note down 5 carry 5).
Step 3: Again (4 x 2 + 3 x 5 + 5 x 7 + 5 (add carry)) = 63 (note down 3 carry 6).
Step 4: Again do cross multiplication and add carry (5 x 2 + 3 x 7 + 6) = 37 (note down 7 carry 3).
Step 5: do multiplication of left numbers and add carry  (3 x 2 + 3) = 9, note it down.
And finally the result we get 97350.


Example #3 – Multiplication of Three Digit Numbers
395 x 284 = ?
The result of multiplication of three digit number is 395 x 284 = 112180.
Step 1: Multiply (4 x 5) = 20 (note down 0 carry 2).
Step 2: Then do cross multiplication(4 x 9 + 8 x 5 + 2 (add carry)) = 78 (note down 8 carry 7).
Step 3: Again (4 x 3 + 2 x 5 + 8 x 9 + 7 (add carry)) = 101 (note down 1 carry 10).
Step 4: Again do cross multiplication and add carry (8 x 3 + 2 x 9 + 10) = 52 (note down 2 carry 5).
Step 5: do multiplication of left numbers(2 x 3 + 5) = 11, note it down.
And finally the result we get 112180.


Example #4 – Multiplication of Three Digit Numbers
175 x 157 = ?
The result of multiplication of three digit number is 175 x 157 = 27475.
Step 1: Multiply (5 x 7) = 35 (note down 5 carry 3).
Step 2: Then do cross multiplication (7 x 7 + 5 x 5 + 3 (add carry)) = 77 (note down 7 carry 7).
Step 3: Again (1 x 7 + 1 x 5 + 7 x 5 + 7 (add carry)) = 54 (note down 4 carry 5).
Step 4: do cross multiplication and add carry (1 x 5 + 1 x 7 + 5 (add carry)) = 17 (note down 7 carry 1).
Step 5: Again (1 x 1 + 1) = 2, note it down.
And finally the result we get 27475.
