Vedic Math Tricks-Multiplying  a number by same number of 9's

In this blog we will learn Vedic Math Trick for Multiplying  a number by same number of 9's. Here we will adopt the method which is different from what we have learnt in our schools.

To multiply a number, with the same number of 9's as there are number of digits in the number let us start with an example.

Suppose we want to multiply 437 with 999. Note that the number of 9's is the same as the number of digits in 437. Follow the below steps :

Step -1 Subtract 1 from the number 437. i.e 437 - 1 = 436

Step -2 Subtract 437 from 1000 i.e. 1000 - 437 = 563

For subtraction, you can follow the same Vedic method as we have learnt in one of our blogs.

Step -3 Combine the results from both the steps i.e 436 and 563.

Therefore, 437 x 999 = 436563

Another example

Let us try the same method with one more example i.e 1769 x 9999 

Step-1 Subtract 1 from the number 1769. i.e 1769 - 1 = 1768

Step -2 Subtract 769 from 1000 i.e. 1000 - 1769 = 8231

For subtraction, you can follow the same Vedic method as we have learnt in one of our blogs.

Step -3 Combine the results from both the steps i.e 1768 and 8231.

Therefore, 1769 x 9999 = 17688231

Try yourself for the below :

1. 24 x 99 

2. 564 x 999

3. 4832 x 9999
