How to Square & Multiply Numbers Quick & Easily – Vedic Mathematics Method

Part 1): A simple and quick method on How to square a number ending with 5.

In this tutorial we are going to learn one simple method of Vedic mathematics to make the square of a number which ends with 5.

Whenever a number ends with 5, definitely the last two digits will be 25. Now the remaining part of the answer can be calculated by multiplying a number with its next. For example if the given number is 35 then first part will be 25 and the remaining part will be 3Ã—4=12. So the answer is 1225.

Example: Find square of 15.

Here the last two digits will be 25 and the first two digits are calculated by 1Ã—2=02. So the answer is 225.

Let us take another example for clear understanding.

Example: Find square of 65.

Solution: first part will be 6Ã—7=42. So the answer is 4225.

Part 2): Multiplication of two numbers having first digit same and last digits add up to 10.

Example: Multiply 46Ã—44.

Solution:

• Bothe numbers having digit 4 same.
• Last digits that are 6 and 4 add up to 10.
• So we just multiply 4Ã—5 =20 for getting first part of the answer.
• Also multiply last digits (6Ã—4=24) for second part of the answer.
• So the answer is 2024.

Example: Multiply 71Ã—79.

Solution:

• Bothe numbers having digit 7 same.
• Last digits that are 1 and 9 add up to 10.
• So we just multiply 7Ã—8=56 for getting first part of the answer.
• Also multiply last digits (9Ã—1=09) for second part of the answer.
• So the answer is 5609.
