Vedic
Mathematics
Vedic
Mathematics is the name given to the ancient system of Mathematics which was
rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krsna Tirthaji
(18841960). According to his research all of mathematics is based on sixteen
Sutras or wordformulae. For example, 'Vertically and Crosswise` is one of
these Sutras. These formulae describe the way the mind naturally works and are
therefore a great help in directing the student to the appropriate method of
solution.
Perhaps
the most striking feature of the Vedic system is its coherence. Instead of a
hotchpotch of unrelated techniques the whole system is beautifully
interrelated and unified: the general multiplication method, for example, is
easily reversed to allow oneline divisions and the simple squaring method can
be reversed to give oneline square roots. And these are all easily understood.
This unifying quality is very satisfying, it makes mathematics easy and
enjoyable and encourages innovation.
In the
Vedic system 'difficult' problems or huge sums can often be solved immediately
by the Vedic method. These striking and beautiful methods are just a part of a
complete system of mathematics which is far more systematic than the modern
'system'. Vedic Mathematics manifests the coherent and unified structure of
mathematics and the methods are complementary, direct and easy.
The
simplicity of Vedic Mathematics means that calculations can be carried out
mentally (though the methods can also be written down). There are many
advantages in using a flexible, mental system. Pupils can invent their own
methods, they are not limited to the one 'correct' method. This leads to more
creative, interested and intelligent pupils.
Interest
in the Vedic system is growing in education where mathematics teachers are
looking for something better and finding the Vedic system is the answer.
Research is being carried out in many areas including the effects of learning
Vedic Maths on children; developing new, powerful but easy applications of the
Vedic Sutras in geometry, calculus, computing etc.
But the
real beauty and effectiveness of Vedic Mathematics cannot be fully appreciated
without actually practising the system. One can then see that it is perhaps the
most refined and efficient mathematical system possible.
The
Vedic Mathematics Sutras

list of the sixteen Sutras in Sanskrit, but in some cases a translation of the
Sanskrit is not given in the text and comes from elsewhere.

At the Maharishi School
in Lancashire we have developed a course on
Vedic mathematics for key stage 3 that covers the national curriculum. The
results have been impressive: maths lessons are much livelier and more fun, the
children enjoy their work more and expectations of what is possible are very
much higher. Academic performance has also greatly improved: the first class to
complete the course managed to pass their GCSE a year early and all obtained an
A grade.
Vedic
maths comes from the Vedic tradition of India. The Vedas are the most
ancient record of human experience and knowledge, passed down orally for
generations and written down about 5,000 years ago. Medicine, architecture,
astronomy and many other branches of knowledge, including maths, are dealt with
in the texts. Perhaps it is not surprising that the country credited with
introducing our current number system and the invention of perhaps the most
important mathematical symbol, 0, may have more to offer in the field of maths.
The
remarkable system of Vedic maths was rediscovered from ancient Sanskrit texts
early last century. The system is based on 16 sutras or aphorisms, such as:
"by one more than the one before" and "all from nine and the
last from 10". These describe natural processes in the mind and ways of
solving a whole range of mathematical problems. For example, if we wished to subtract
564 from 1,000 we simply apply the sutra "all from nine and the last from
10". Each figure in 564 is subtracted from nine and the last figure is
subtracted from 10, yielding 436.
This
can easily be extended to solve problems such as 3,000 minus 467. We simply
reduce the first figure in 3,000 by one and then apply the sutra, to get the
answer 2,533. We have had a lot of fun with this type of sum, particularly when
dealing with money examples, such as £10 take away £2. 36. Many of the children
have described how they have challenged their parents to races at home using
many of the Vedic techniques  and won. This particular method can also be
expanded into a general method, dealing with any subtraction sum.
The
sutra "vertically and crosswise" has many uses. One very useful
application is helping children who are having trouble with their tables above
5x5. For example 7x8. 7 is 3 below the base of 10, and 8 is 2 below the base of
10.
The
whole approach of Vedic maths is suitable for slow learners, as it is so simple
and easy to use.
The
sutra "vertically and crosswise" is often used in long
multiplication. Suppose we wish to multiply
32 by 44. We multiply vertically 2x4=8.
Then we multiply crosswise and add the two results: 3x4+4x2=20, so put down 0 and carry 2.
Finally we multiply vertically 3x4=12 and add the carried 2 =14. Result: 1,408.
32 by 44. We multiply vertically 2x4=8.
Then we multiply crosswise and add the two results: 3x4+4x2=20, so put down 0 and carry 2.
Finally we multiply vertically 3x4=12 and add the carried 2 =14. Result: 1,408.
All the techniques produce oneline answers and most can be dealt with mentally, so calculators are not used until Year 10. The methods are either "special", in that they only apply under certain conditions, or general. This encourages flexibility and innovation on the part of the students.
Multiplication can also be carried out starting from the left, which can be better because we write and pronounce numbers from left to right. Here is an example of doing this in a special method for long multiplication of numbers near a base (10, 100, 1,000 etc), for example, 96 by 92. 96 is 4 below the base and 92 is 8 below.
We can crosssubtract either way: 968=88 or 924=88. This is the first part of the answer and multiplying the "differences" vertically 4x8=32 gives the second part of the answer.
This works equally well for numbers above the base: 105x111=11,655. Here we add the differences. For 205x211=43,255, we double the first part of the answer, because 200 is 2x100.
We regularly practise the methods by having a mental test at the beginning of each lesson. With the introduction of a noncalculator paper at GCSE, Vedic maths offers methods that are simpler, more efficient and more readily acquired than conventional methods.
There is a unity and coherence in the system which is not found in conventional maths. It brings out the beauty and patterns in numbers and the world around us. The techniques are so simple they can be used when conventional methods would be cumbersome.
When the children learn about Pythagoras's theorem in Year 9 we do not use a calculator; squaring numbers and finding square roots (to several significant figures) is all performed with relative ease and reinforces the methods that they would have recently learned.

Book review of 'Fun with Figures'
From 'inTouch', Jan/Feb 2000, the Irish National Teachers Organisation (INTO) magazine.
"Entertaining, engaging and eminently 'doable', Williams' pocket volume reveals many fascinating and useful applications of the ancient Eastern system of Vedic Maths. Tackling many number operations encountered between First and Sixth class, Fun with Figures offers several speedy and simple means of solving or doublechecking class activities. Focusing throughout on skills associated with mental mathematics, the author wisely places them within practical liferelated contexts." "Compact, cheerful and liberally interspersed with amusing anecdotes and aphorisms from the world of maths, Williams' book will help neutralise the 'menace' sometimes associated with maths.
It's practicality, clear methodology, examples, supplementary exercises and answers may particularly benefit and empower the weaker student." "Certainly a valuable investment for parents and teachers of children aged 7 to 12." Reviewed by Gerard Lennon, Principal, Ardpatrick NS, Co Limerick.

Vedic Maths Tutorial
Vedic Maths is based on sixteen Sutras or principles. These principles are general in nature and can be applied in many ways. In practice many applications of the sutras may be learned and combined to solve actual problems. These tutorials will give examples of simple applications of the sutras, to give a feel for how the Vedic Maths system works.
These tutorials do not attempt to teach the systematic use of the sutras.
For more advanced applications and a more complete coverage of the basic uses of the sutras, we recommend you study one of the texts available at www.vedicmaths.org
N.B. The following tutorials are based on examples and exercises given in the book 'Fun with figures' by Kenneth Williams, which is a fun introduction to some of the applications of the sutras for children.
Tutorial 1
Tutorial 2

Tutorial 4
Tutorial 5
Tutorial 6
Tutorial 7
Tutorial 8 (By Kevin O'Connor)
Tutorial 1
Use the formula ALL FROM 9 AND THE LAST FROM 10 to
perform instant subtractions.
For example 1000  357 = 643
We simply take each figure in 357 from 9 and the last figure from 10.
So the answer is 1000  357 = 643
And thats all there is to it!
This always works for subtractions from numbers consisting of a 1 followed by noughts: 100; 1000; 10,000 etc.
Similarly 10,000  1049 = 8951
For 1000  83, in which we have more zeros than
figures in the numbers being subtracted, we simply
suppose 83 is 083.
So 1000  83 becomes 1000  083 = 917
Exercise 1 Tutorial 1
Try some yourself:
1) 1000  777 =
2) 1000  283 =
3) 1000  505 =
4) 10,000  2345 =
5) 10,000  9876 =
6) 10,000  1011 =
7) 100  57 =
8) 1000  57 =
9) 10,000  321 =
10) 10,000  38 =
Tutorial 2
Using VERTICALLY AND CROSSWISE you do
not need the multiplication tables beyond 5 X 5.
Suppose you need 8 x 7
8 is 2 below 10 and 7 is 3 below 10.
Think of it like this:
The answer is 56.
The diagram below shows how you get it.
You subtract crosswise 83 or 7  2 to get 5,
the first figure of the answer.
And you multiply vertically: 2 x 3 to get 6,
the last figure of the answer.
That's all you do:
See how far the numbers are below 10, subtract
one number's deficiency from the other number,
and multiply the deficiencies together.
7 x 6 = 42
Here there is a carry: the 1 in the
12 goes over to make 3 into 4.
Exercise 1 Tutorial 2
Multply These:
1) 8 x 8 =
2) 9 x 7 =
3) 8 x 9 =
4) 7 x 7 =
5) 9 x 9 =
6) 6 x 6 =
Answers to exercise 1 tutorial 2
Here's how to use VERTICALLY AND CROSSWISE
for multiplying numbers close to 100.
Suppose you want to multiply 88 by 98.
Not easy,you might think. But with
VERTICALLY AND CROSSWISE
you can give the answer immediately,
using the same method as above
Both 88 and 98 are close to 100.
88 is 12 below 100 and 98 is 2 below 100.
You can imagine the sum set out like this:
As before the 86 comes from subtracting crosswise:
88  2 = 86 (or 98  12 = 86: you can subtract either way,
you will always get the same answer).
And the 24 in the answer is just 12 x 2: you
multiply vertically.
So 88 x 98 = 8624
Exercise 2 Tutorial 2
This is so easy it is just mental arithmetic.
Try some:
1) 87 x 98 =
2) 88 x 97 =
3) 77 x 98 =
4) 93 x 96 =
5) 94 x 92 =
6) 64 x 99 =
7) 98 x 97 =

Multiplying numbers just over 100.
103 x 104 = 10712
The answer is in two parts: 107 and 12,
107 is just 103 + 4 (or 104 + 3),
and 12 is just 3 x 4.
Similarly 107 x 106 = 11342
107 + 6 = 113 and 7 x 6 = 42
Exercise 3 Tutorial 2
Again, just for mental arithmetic
Try a few:
1) 102 x 107 =
2) 106 x 103 =
3) 104 x 104 =
4) 109 x 108 =
5) 101 x123 =
6) 103 x102 =

Tutorial 3
The easy way to add and subtract fractions.
Use VERTICALLY AND CROSSWISE
to write the answer straight down!
Multiply crosswise and add to get the top of the answer:
2 x 5 = 10 and 1 x 3 = 3. Then 10 + 3 = 13.
The bottom of the fraction is just 3 x 5 = 15.
You multiply the bottom number together.
So:
Subtracting is just as easy: multiply
crosswise as before, but the subtract:

A quick way to square numbers that end in 5 using
the formula BY ONE MORE THAN THE ONE BEFORE.
75^{2} = 5625
75² means 75 x 75.
The answer is in two parts: 56 and 25.
The last part is always 25.
The first part is the first number, 7, multiplied
by the number "one more", which is 8:
so 7 x 8 = 56
Similarly 85^{2} = 7225 because 8 x 9 = 72.

Method for multiplying numbers where the first
figures are the same and the last figures add up to 10.
32 x 38 = 1216
Both numbers here start with 3 and the last figures (2 and 8) add up to 10.
So we just multiply 3 by 4 (the next number up)
to get 12 for the first part of the answer.
And we multiply the last figures: 2 x 8 = 16 to
get the last part of the answer.
Diagrammatically:
And 81 x 89 = 7209
We put 09 since we need two figures as in all the other examples.

Tutorial 5
An elegant way of multiplying numbers using a simple pattern
21 x 23 = 483
This is normally called long multiplication but actually
the answer can be written straight down using the
VERTICALLY AND CROSSWISEformula.
We first put, or imagine, 23 below 21:
There are 3 steps:
a) Multiply vertically on the left: 2 x 2 = 4.
This gives the first figure of the answer.
b) Multiply crosswise and add: 2 x 3 + 1 x 2 = 8
This gives the middle figure.
c) Multiply vertically on the right: 1 x 3 = 3
This gives the last figure of the answer.
And thats all there is to it.
Similarly 61 x 31 = 1891
6 x 3 = 18; 6 x 1 + 1 x 3 = 9; 1 x 1 = 1
Exercise 1 Tutorial 5
Try these, just write down the answer:
1) 14 x 21
2) 22 x 31
3) 21 x 31
4) 21 x 22
5) 32 x 21
