# Mathemagic

Participants of recently held workshops on Vedic Mathematics in Thane were blown away by this ancient system of mathematics, almost as if they had found magic mantras. For those unfamiliar with Vedic maths, the set of 16 algorithms and 14 sub-algorithms in Sanskrit meant for performing simple and complex computations, are no less than magic.

The growing popularity of Vedic Mathematics among Thaneites is simply a reflection of a worldwide phenomenon. Even students from the prestigious Indian Institutes of Technology (IITs) are said to be relying on these ancient techniques for quick mental calculations. So what makes Vedic Maths such a winner?

Vilas Sutavane, who regularly conducts these workshops in Thane, believes that Vedic Mathematics is India’s gift to the world. It is well known that foundation of modern mathematics was established in India. The Vedas, written around 1500-900 BC, are ancient Indian texts containing a record of human experience and knowledge. Thousands of years ago, Vedic mathematicians authored various theses and dissertations on mathematics. It is now commonly believed and widely accepted that these treatises laid down the foundations of algebra, algorithm, square roots, cube roots, various methods of calculation, and the concept of zero.

The term Vedic mathematics refers to the group of sixteen sutras (algorithms) written by Swami Bharathi Krishna Tirthaji. These algorithms help solve all mathematical problems in pure and applied mathematics. Practitioners of this striking method of mathematical problem-solving opine that Vedic maths is far more systematic, coherent and unified than the conventional system. Complexly arranged modern mathematical problems can easily be solved by simple mental mathematics through these methods. The solutions can be obtained much faster than any other method – a reason behind its enormous popularity among educationists and academicians.

Now you need never rely on calculators to do arithmetic. All you need is a crash course in Vedic Mathematics. To find out more about Vedic Mathematics workshops in Thane, readers can call 25400859 or 25383483.

**Try these out…**One More than the One Before

For multiplying numbers like 74 x 76 where the first digits are the same and the last digits add up to 10, you multiply 7 by the number "One More", which is 8. So 7×8=56 is the left part of the answer. And then multiply the last by the last to get 4×6=24 as the last part of the answer. This gives 74 x 76 = 5624.

If you want to find the square of 45, you can employ the same principle (called Ekadhikena Purvena sutra in Sanskrit). The rule says since the first digit is 4 and the second one is 5, you will first have to multiply 4 (4 +1), that is 4 X 5, which is equal to 20 and then multiply 5 with 5, which is 25. Voila! The answer is 2025. Now, you can employ this method to multiply all numbers ending with 5.

Multiplying a number by 11

To multiply any 2-figure number by 11 we just put the total of the two figures between the 2 figures (for numbers whose sum is greater than 9, there is a slight variation).

26 x 11 = 286

Notice that the outer figures in 286 are the 2 & 6.

And the middle figure is just 2 and 6 added up.
