This issue's article is by Anand Pattabiraman, an eleven year old sixth grader enrolled in the ROGATE Program (Resources Offered for Gifted And Talented Education) of the National Talent Network, in Tenafly, New Jersey, USA, who has conducted research on Vedic Math.

## RESEARCH IN VEDIC MATH

In spring of 2003, Anand Pattabiraman conducted research on a topic called Vedic Math. Vedic Math was said to be a fast way to do arithmetic and he wished to see if this was true.
Ancient Indian mathematicians made numerous contributions to mathematics such as Vedic Math. The decimal system and the concept of zero were other major contributions. The advanced system of Vedic Math is believed to be described in the Parasista (Par - a - shish -tha), the appendix portion of the Atharvatheva, one of the 4 Veda books. The Vedic Math system was rediscovered in the 20th century by Jagadguru Swami Sri Bharati Krishna Tirthaj Maharaja.
For his ROGATE Research Project, Anand selected Vedic Math as the topic. He did some preliminary research and formulated his hypothesis. He found two primary and two secondary resources to complete his research. He designed and conducted an experiment. He collected and analyzed the data and finally created his presentation and report.
The hypothesis that Anand formulated was: Students who use Vedic Math are quicker and more accurate when doing computations. The primary resources that he used to research this hypothesis were an interview with Kenneth Williams, a Vedic Math scholar and mathematician, and an experiment involving six 6th grade students who were advanced in mathematics. The secondary resources were three websites online and a newspaper article.
As one of Anand's primary resources, he contacted Dr. Kenneth Williams, Vedic Math scholar and mathematician, and interviewed him on the topic of Vedic Math. Dr. Williams stated that Vedic Math can and does apply to all mathematical problems.
But how can Vedic Math apply to all mathematical problems when there are just 16 sutras (rules)? Dr. Williams explained "These seem to relate to the way the mind works and that is the reason why there are 16 sutras as there are just 16 ways that the mind can function and from that point of view, the Vedic math must cover all of math if these 16 functions cover all the ways in which we think, then it must be a complete system."
But could there be any disadvantages that could make teachers not want to teach Vedic Math to students? "Doing mental maths increases your brain power and your mental agility and creativity, it's really an advantage, there aren't really any disadvantages.", Dr. Williams told Anand.
But is Vedic Math right for everyone? Dr. Williams declared "Oh certainly, it should be used everywhere it's a much more coherent system, much easier to use, more flexible. Children who are slow at math find it easy and kids who are good at math find that they like it as well, everybody seems to like it. It has been demonstrated that people do get higher grades and win awards who do Vedic Math."
All of the information Anand Pattabiraman found online agreed with what Dr. Williams cited and had only positive opinions regarding Vedic Math. "The beautiful system of Vedic Mathematics is far more unified and direct than conventional mathematics.", Dr. Williams expounded, adding that "exceedingly tough mathematical problems …can be easily and readily solved with the help of these ultra-easy Vedic Sutras. The Sutras (aphorisms) apply to and cover ...every branch of mathematics …. In fact, there is no part of mathematics, pure or applied, which is beyond their jurisdiction."
Dr. Williams exclaimed "It is so fascinating, it has turned math-haters into math-lovers!" Anand Pattabiraman was very surprised by all this information.
For his experiment, Anand selected three out of the 16 sutras. These three sutras helped with adding and subtracting fractions, multiplying with numbers close to 100, and subtracting from numbers in the series 10, 100, 1000, etc. He created a test involving the uses of these three sutras. The test had 30 problems with ten problems for each of the sutras. Three 6th grade students were given this test and were supposed to use their own method of arithmetic. Three other 6th graders were taught the Vedic Math guidelines and then given the same test. During all the tests, the completion time was noted and the tests were scored for accuracy. In addition, the students who learned Vedic Math were also given a questionnaire to see their reaction to Vedic Math.

RESULTS

Control Group Time (minutes) Accuracy
Subject #1 8:26                       30/30
Subject #2 13:53                     28/30
Subject #3 14:32                     24/30
Average 12:28                         27/30

Experimental Group Time (minutes) Accuracy
Subject #1 6:36                               27/30
Subject #2 11:33                             29/30
Subject #3 14:58                             25/30
Average 11:03                                 27/30

The average completion time of the control group, i.e. the kids who were not taught, was 12:28 minutes, while the experimental group, the kids who were taught Vedic Math, had an average of 11:03 (minutes). Therefore the experimental group was 11.5% faster than the control group.
The efficiency for each subject was calculated by dividing the %accurate answers by the time taken to complete the test. Then the average efficiency for each group was calculated (Control = 8.02, Experimental = 9.19). The conclusion is that the experimental group was still 15% more efficient than the control group, even though they had the same average score.
After the tests were taken and times recorded, children in the control group were taught the rules of Vedic Math (optional). It appeared that the only student who had scored 30/30 in this experiment belonged to the control group and she had already learnt 2 out of the 3 rules and used it in the test. This suggests that Vedic Math could be taught in other places, it is just not known by the title Vedic Math. This person should really have been part of the experimental group and could have boosted the accuracy of the experimental group even further.
At the end, Anand Pattabiraman conducted a survey on the kids who were taught Vedic Math. Some of the questions and answers are listed here. Two out of the three sixth graders agreed that the Vedic Math rules were useful it but the third student Anand attempted to teach said "Yeah, the ways of doing Vedic math were cool… but, it didn't really help me." This person didn't want to participate in the experiment. All three of the sixth graders thought it was cool and liked it. They were undecided whether it should be used in schools but one was sure, "Maybe, it will be sort of hard if kids don't know their basics." "Yes, it can help other kids solve problems easier, too." All of them agreed that they would remember some of it and use it again.
Anand concluded that his data and research support his hypothesis that Students who use Vedic Math are quicker and more accurate when doing computations.

How can this research be applied to new situations?
The Vedic Math system can be used in schools around the world.
The system will be easier for teachers to teach and students to use.
It can also be used to train math teams for competitions where speed and accuracy count.

ARTICLE

An excellent article has been published in Australia in the Global Journal of Engineering Education, Vol. 8, No. 2., 2004 (which belongs to UNESCO International Centre for Engineering Education (UICEE) & published from Melbourne - Wismar 2004, Australia).. Authors are Purushottam D. Chidgupar and Mangesh T. Karad.

Some quotes:

Digital signal processing (DSP) is the technology that is omnipresent in almost every engineering discipline. It is also the fastest growing technology this century and therefore, it poses tremendous challenges to the engineering community. Faster additions and multiplications are of extreme importance in DSP for convolution, discrete Fourier transforms, digital filters etc. The core computing process is always a multiplication routine; therefore, DSP engineers are constantly looking for new algorithms and hardware to implement them.

Two-digit yields….a time saving of approximately 59% can be achieved using the Vedic method. In the case of three-digit multiplication, approximately 42% of the processing time is saved. Similar results can be obtained on other processes as well.

Therefore, such approaches are extremely beneficial in DSP applications. There is an overwhelming need to explore Vedic algorithms in detail so as to verify its applicability in different domains of engineering.
Vedic algorithms implementations on specially designed BCD architecture will also help to enhance processor throughput.
An awareness of Vedic mathematics can be effectively increased if it is included in engineering education. In future, all major universities may set up appropriate research centres to promote research works in Vedic mathematics.
