# VEDIC MATHEMATICS NEWSLETTER

ISSUE No. 53

A warm welcome to our new subscribers. Vedic Mathematics is becoming increasingly popular as more and more people are introduced to the beautifully unified and easy Vedic methods. The purpose of this Newsletter is to provide information about developments in education and research and books, articles, courses, talks etc., and also to bring together those working with Vedic Mathematics. If you are working with Vedic Mathematics - teaching it or doing research - please contact us and let us include you and some description of your work in the Newsletter. Perhaps you would like to submit an article for inclusion in a later issue or tell us about a course or talk you will be giving or have given. If you are learning Vedic Maths, let us know how you are getting on and what you think of this system.

**Squaring numbers ending in 4**

In the previous newsletter readers were

challenged to find a method for squaring numbers

ending in 4 that followed the method for squaring

numbers ending in 5. We received two responses,

both neat and using the same principle as for

squaring numbers ending in 5. They are given below. Thanks to both of you.

1) From Balan V Iyer

The method is very simple. It would be the same

as for squaring any number ending in 9 using the

algebraic identity (a+b) squared = a2 + 2ab + b2

and (a - b) squared = a2 - 2ab - b2. To give an

example, 14 squared = (15 - 1) 2 i.e. 225 - 30 +

1 = 196. As we know the squares of numbers

ending in 0 and 5 mentally, working out mentally

squares of numbers ending in 1, 9, 4 and 6 could

be mentally performed using the above

identity. I trust this explanation would help.

2) From David

One method might be:

Let the number in front of the 4 be N

Multiply N by N+1, add two zeroes

Subtract (2N-1)*10

Add 6

Example 74*74

7*8=56 5600

Subtract (2*7-1)*10= 130

5470

Add 6

5476

One could shorten it to

Multiply N by N+1, add 06 to RHS

Subtract (2N-1)*10

Example 204*204

20*21=420 42006

Subtract (2*20-1)*10=390

41616

Example 364*364

36*37=1332

133206

Subtract (2*36-1)*10=710

132496

Interestingly one can find similar methods for any end digit.

For example

66*66

6*7=42 : 4206

Add (2*6+3)*10=150

4356

79*79

7*8=56 : 5601

Add (8*7+8)*10=640

6241

Kenneth, considering the method I sent it might

be easier to remember in this form as it more

closely matches the method for numbers ending in 5.

Number N*10 + 4

Write down N*(N+1) and put 16 (4 squared) on the RHS

Subtract 2*N*10 from that number.

EG: 74x74

7*8=56 => 5616

Subtract 2*7*10=140

**WORKSHOP IN KOLKATA** - Overview by Bhavna Malhotra

World Academy in association with “Health Shoppe”

(a unique health and lifestyle product outlet

based in Kolkata.) which incidentally is a

division of Nantra Retailing Limited arranged a

workshop on Vedic Mathematics on 27th day of

August 2006 at 3 p.m. at premises of the Health

Shoppe. The said workshop was conducted by

Debmalya Banerjee, a popular faculty of the

academy on the subject from Kolkata.

The workshop which spanned little more than three

hour was inaugurated by noted Indian Sculptress

Uma Siddhanta and was attended by around 20 people.

The response of the crowd was overwhelming. Lot

of questions were asked as the workshop had

interactive session too. He also narrated to the

crowd the kind of activities the academy has done

in the past and what it intends to do in future.

He also told the crowd in brief what activities

are going on globally on the subject.

The expert explained Nikhilam Methods of

Calculation, multiplication by 11,Digital roots,

Rule of 9, 99, 999, Ekadhikena Purvena as well as

Urdhava Method.The expert explained the nuances

of the subject by carrying out calculations using

Vedic Sutras and frequently comparing those

calculations with the western system of Mathematics.

A coverage of the said event was published by a

renowned regional daily a week later.

“Health Shoppe” plans to have more workshops in

association with the academy as there is a growing demand for the same.

**KOLKATA WORKSHOP** - Overview by Dr.Partha Chatterjee

The 4th Gandhi Inter school Summer Camp jointly

sponsored by Gandhi Smriti and Darshan Samity New

Delhi and SIPDAVE Kolkata was held on June 3-4,

2006 at the Eastern Zonal Cultural Centre

Auditorium-Aikyatan, Salt Lake, Kolkata. 50

students from 15 schools of Kolkata between the

age group 13 and 15, 5 teachers and about 30

guardians participated in the camp. The camp was

inaugurated by Sabyasachi Chakraborty, the famous

Bengali actor. Some other popular celebrities of West Bengal were also present.

A lecture on Vedic Mathematics was given by

Debmalya Banerjee, a renowned and popular faculty

of the Academy at the camp. The lecture spanned

little more than an hour. The faculty gave a

detailed idea about what exactly is Vedic

Mathematics and how it can be useful. He also

briefed the audience vividly about WAVM, its key

members, panel of faculties and the kind of

activities the Academy is involved in. The

audiences were told about the kind of activities

that are taking place globally, and the kind of

books and the courses that are available.

The expert explained Nikhilam Methods of

Calculation, multiplication by 11, Multiplication

by 9, 99,999 and the Urdhava Method.

The workshop was greatly appreciated by the

participants and the expert had a harrowing time

satisfying the autograph hunter kids. A review

with a specific mention about Vedic Mathematics

was also published by a frontline newspaper of the region.

*** FROM DR BRIAN MCENERY**

Dear Kenneth, I just found a copy of an e-mail

that you sent me on 10 June 2004, it was a

printed copy, and contained a part of a

discussion between Dr Dikshit Vice-Chancellor of

IGNOU and Dr. Shukla (from NCERT). The flaw in

their reasoning is that the Universe and us as

part of it is not guided by logic alone. Geoorge

Boole the founder of modern Mathematical Logic,

and Professor of Mathematics at University

College Cork, made a fatal flaw when he divided

the sheep into two flocks, one black and the

other white, he seemed to ignore the

infinitesimal gradations in the reality of

nature. Our minds being a part of the creative

process in nature must also be encouraged to

wander and seek the pleasure that are in the real

garden of mathematics. Some time ago I

communicated with Howard Gardiner, the founder of

Multiple Intelligences, suggesting that the

stable creative core of intelligence should form

part of his theory. We had a very cordial series of e-mails.

In a sense pure mathematics is now guided by the

very constrained laws of mathematical logic, but

computation is much more a discipline of the

practical application of knowledge, where skill,

art, and logic are used in equal measure. When I

used to teach courses in Fortran, I always

encouraged my students to take as much care with

the layout and structure of their programs, as

with just getting the job done. I said that the

program should flow like a poem. This discipline

ensures the development of skill and clarity in

expressing the underlying computational process.

In fact modern computation has to a large extent

superseded traditional mathematical logic, and it

is here that the vedic sutras are so powerful as

they provide patterns in computation which are

both universal and simple to teach to students of

all ages. The purely logical approach makes it

very difficult to create new approaches, as the

student is constantly concerned with making a

mistake. The corrective techniques, and

multiplicity of approaches inherent in Vedic

Mathematics ensure that every wrong answer is an

opportunity for further exploration.
