What is Vedic Math?

It is a relatively new term that has been introduced into the lexicon only in the last fifty years. Re-discovered during the period 1911-1918 by a brilliant mathematician, philosopher and educator Jagadguru Swami Sri Bharathi Krsna Tirtha Maharaj, Shankaracharya of Govardhana Math, Puri.

It consists of a set of sixteen aphorisms or formulae (sutras) and thirteen sub-aphorisms. This has been highlighted in a book published posthumously in 1965 under the title “Vedic Mathematics”. This approach according to the author’s own account, he distilled the sutras from the `mathematical formulae’ from ancient Indian philosophical and religious texts from Atharva-Veda (one of the four treatises –Rig, Yajur and Sama being the others) that deals primarily with worldly aspects.

Why Vedic Math?

It is totally unconventional, simple and fun to work with.

Leads to efficient superfast calculations.

No memorisation of tables.

Saves time and very flexible.

Offers a large number of alternatives for almost every field like trignometry, arithmetic, geometry, calculus, differential equations, etc.

Let us see few applications below..

Secret of Division (by 9) :

Multiples of 11 : Simple trick

Here I’ll tel you how to do multiples of 11 as fast as 1 + 1.

There are two ways; one is for the single digit numbers and other is for the double digit numbers.  Now you all probably already know the first method (for single-digit). You just have to put the same number next to the single digit number.

For Example: 6 times 11 = ??

We simply write 6 x 11 = 66

Now let us see what is the secret to calculate when it comes to double digit numbers..

STEP 1 : Take the ‘SUM’ of both the digits of the given number. For Example: 45 times 11 = ???  Then, 4 + 5 = 9.

STEP 2 : Place this 9 in between (tens place) the given double digit numbers (45). i.e. 495

So we get 45 x 11 = 495  as the answer! 

Isn’t that interesting, swift, time-efficient. As we all here on deals with 64-square and since many say Mathematics helps improve chess-skills; this might help us. Since end-games have limited pieces on board, I have started studying "End-Games" from mathematical point of view.
