What is Vedic Mathematics? Is Vedic Mathematics any Useful For Us in Today's Modern Times?

Vedic Mathematics is an ancient system of mathematics that finds its roots in the Vedas, the ancient Hindu scriptures written in Sanskrit. The system was rediscovered and popularized by the Indian mathematician Bharati Krishna Tirthaji Maharaj in the early 20th century. He claimed to have reconstructed the system from the Vedas, specifically the Atharva Veda. 

Key Features of Vedic Mathematics

1. Sutras (Formulas): 

  Vedic Mathematics is based on 16 main sutras (aphorisms) and 13 sub-sutras (sub-aphorisms). These sutras are essentially formulae that describe ways to solve mathematical problems. Each sutra deals with a different type of problem, ranging from arithmetic to algebra, geometry, and calculus.

2. Mental Calculation:

   One of the distinguishing features of Vedic Mathematics is its focus on mental calculation. The techniques are designed to be performed in one's head, making it faster than conventional methods.

3. Flexibility:

   The methods are highly flexible and can often be applied in multiple ways to the same problem. This adaptability makes it a useful tool for a variety of mathematical challenges.

4. Simplicity and Speed:

   The techniques simplify complex calculations and reduce them to basic, easy-to-follow steps. This leads to quicker results and often more efficient problem-solving.

Basic Techniques and Examples

1. Vertically and Crosswise:

   This is a common sutra used for multiplication. For example, to multiply 23 by 21, you would use the following steps:

   - Multiply the last digits: 3 × 1 = 3.

   - Cross-multiply and add: (2 × 1) + (3 × 2) = 2 + 6 = 8.

   - Multiply the first digits: 2 × 2 = 4.

   - Combine the results: 483.

2. Nikhilam Sutra:

   This sutra is used for multiplying numbers that are close to a base, such as 10, 100, 1000, etc. For example, to multiply 98 by 97 (both close to 100):

   - Subtract each number from the base: 100 - 98 = 2, and 100 - 97 = 3.

   - Multiply the differences: 2 × 3 = 6.

   - Subtract one number’s difference from the other original number: 98 - 3 = 95.

   - Combine the results: 9506.

3. All from 9 and the Last from 10:

   This sutra is used for subtraction from a power of 10. For example, to subtract 357 from 1000:

   - Subtract each digit from 9, except the last digit from 10: (9-3), (9-5), (10-7) = 643.


Applications of Vedic Mathematics

1. Education:

   Vedic Mathematics is increasingly being used in schools to teach arithmetic and algebra. Its methods help improve students’ mental agility and numerical skills.

2. Competitive Exams:

   Due to its speed and efficiency, Vedic Mathematics is often used in preparation for competitive exams where time is a critical factor.

3. Everyday Calculations:

   The techniques are also useful in daily life for quick and easy calculations, such as budgeting, shopping, and cooking measurements.


Criticisms and Controversies

While Vedic Mathematics has many proponents, it has also faced criticism. Some scholars question the historical accuracy of its Vedic origins, arguing that there is little evidence in the ancient texts to support the claims made by Bharati Krishna Tirthaji. Despite this, the practical benefits of the system are widely acknowledged.

In conclusion, Vedic Mathematics offers a unique and efficient approach to solving mathematical problems. Its techniques promote mental agility and can make complex calculations simpler and faster, making it a valuable tool for students and professionals alike.

The Fever of Being Viral

By Arshad Usmani All of us live with our past. All of us allow it to shape our future. But some of us know how to shrug the past. I think that is who I am...  Although I was not like this always until one day which changed my whole life. That was the day when I decided to die and even my parents would have totally supported it.They are that good and believed in me. And that actually keeps me going because I am not the usual. I am weird. Why not, normal is so boring. It's just about perception or any sane being would have looked at my life to gasp in horror and call it dull, miserable and monotonous. But I feel proud when my teachers made me stand in front of the class and said, "Look, this is the student you all should try to become. I am sure you can never be like her as she is one and only. She is the best, been student of the year every year, always topped the class and every competition and this year awaits wonders in inter school board exams for her."  At noon I sat...
