# Vedic Mathematics (speed arithmetic)

**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..

# 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 chess.com 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.
