Multiplying A Number With 18
Using this method we can multiply any number with 18 in a very easy way. Such type of Techniques of Vedic Maths help us to perform calculations in a much faster way. Mastering such type of techniques is very essential in Competitive Exams where time is very precious
For example let us multiply 7248 and 18
Method
We will prefix a 0 before the number. The number becomes 07248. We will multiply the digit at unit place with 8. The unit place of the resultant number will be the unit place in the answer and the remaining will be the carry. Then we will multiply the next number with 8 and add the previous number. The unit place of the resultant number will be prefixed in the answer and remaining will be the carry. The same process is repeated for the next number.

We will Multiply the digit at unit place that is 8 with 8 Resultant Number = 8 X 8 = 64 The unit place of the resultant number will be prefixed in the answer and remaining will be the carry Answer = 4 Carry = 6 |
 |
|
We will Multiply the digit at tens place that is 4 with 8 and add the number at units place. Then add the carry if any Resultant Number = 4 X 8 + 8+ 6 = 40 + 6 = 46 The unit place of the resultant number will be prefixed in the answer and remaining will be the carry Answer = 64 Carry = 4 |

We will Multiply the digit at hundreds place that is 2 with 8 and add the number at tens place. Then add the carry if any Resultant Number = 2 X 8 + 4 + 4 = 20 + 4 = 24 The unit place of the resultant number will be prefixed in the answer and remaining will be the carry Answer = 464 Carry = 2 |
 |
|
We will Multiply the digit at Thousands place that is 7 with 8 and add the number at hundreds place. Then add the carry if any Resultant Number = 7 X 8 + 2 + 2 = 58 + 2 = 60 The unit place of the resultant number will be prefixed in the answer and remaining will be the carry Answer = 0464 Carry = 6 |
 |
|
We will Multiply the digit at Ten Thousands place that is 0 with 8 and add the number at thousands place. Then add the carry if any Resultant Number = 0 X 8 + 7 + 6 = 7 + 6 = 13 The resultant number will be prefixed in the answer Answer = 130464 |
