Abstract
Vedic mathematics is an interesting, speedy, simple logical & integral part of our ancient Indian culture
using traditional mathematics, which finds its origin in our Vedas especially “Atharva Veda” and is
mainly based on 16 principles called “Sutras” & 13 Sub-Sutras. Applied to almost every branch of
mathematics. The interesting part in Vedic mathematics is, you can mostly check your calculation and
know whether you are right or wrong in few seconds and that makes it more enjoyable. Here, discuss
some applications of Vedic mathematics in one of its field i.e. Algebra and see how it saves a lot of time &
efforts in solving the problems.

Here is an example to understand the entire concept
by this simple diagrammatical structure.
2.1.ParavartyaYojayet
Numerator of x Numerator of y Denominator
This method is applicable for all sorts of linear
simultaneous equations. A simple idea for
finding value of x, start with y – coefficient and
independent terms and cross multiply them in b1 c1 a1 b1
the forward direction, the sign between the two
cross multiplication is minus (-). For y, start with
the independent term and x – coefficient and
cross-multiply them in the backward direction.
The sign between the cross-multiplication result b2 c2 a2 b2
is minus (-). For the result of the denominator,
take the coefficient of variable only and cross-
multiply then in backward direction.
Here is an example to understand this concept.
Suppose, have the following set of simultaneous
equations: -
a1x + b1y = c1 Example 1: Simplify for x and y, 3x + 4y = 10;
a2x + b2y = c2 4x - 2y = - 16
In order to get the numerator of x , leave the
coefficient of x and write the coefficient of y and
the independent term and cross multiply them Coefficient of y Independent term
with a minus sign in between the cross product 4 10
in rightward direction as shown here:-[4-6]
b1 c1
-2 -16
b2 c2
= b1 c2 - b2c1 x=
Again, to get numerator of y, leave the
coefficient of y and take only the coefficient of x Coefficient of x Coefficient of y
and the independent term into consideration. As
know the sutra moves in a cyclic order, so start
with independent term first. Cross multiplication 3 4
of the independent term and coefficient of x will
give the numerator of y.

Independent Term Coefficient of x 2.3. Anurupye Sunyamanyat:
This sutra simply says: Addition and subtraction.
10 3 When there is coefficient of x in 1st equation is
equal to the coefficient of y in 2nd equation and
vice versa. This sutra works well. To understand
this here is an example:
-16 4
Example3: Solve for x andy.
Coefficient ofx Coefficient of y 1955x – 476y=2482 ….(A)
3 4 476x – 1955y=-49131 ….(B)
Adding (A) and (B), equation becomes,
2431x - 2431y = - 2431;
-2
x – y=-1 ….(C)
x = -2, y = 4 Subtract (B) from (A):
1479x – 1479y = 7395;
2.2.Anurupye Sunyamanyat:
x + y=5 … (D)
This Vedic sutra says – Add (C) and (D), value of x = 2 subtract (D)
If one is in ratio, the other one is zero, it means from(C), value of y =3.
when the ratio of x or y is equal to that of 3. Conclusion
independent term, put the ratio of y or x = 0. To Therefore, while applying Vedic mathematics one can
understand here is an example: versatility in solving problems and at the same time,
this helps to decide on the best method possible in
Example 2: Simplify for x and y solving a particular type of problem. The beauty of
Vedic mathematics is in its inventiveness, which one
7x + 6y = 70; experiences while applying. As one can see in the
14x+13y above methods that with good practice of the Vedic
mathematics one can do time consuming complex
Problems far more easily and faster.
The ratio of coefficients of x is 1:2 which is equal References
to the ratio of the independent term. So according [1]. Jagadguru Swami Sri Bharati Krisna Tirthaji (1986),
to above sutra, we put y = 0 in either of the Vedic Mathematics or Sixteen Simple Sutras from
equations to get the value of x. the Vedas. Motilal Banarasidas, Varanasi(India).
