Vedic Mathematics is the former system of Mathematics which was formulated and encapsulated in the modern form by
Jagadguru Swami Bharati Krishna Tirtha Ji. During the period of 1919 – 1927 he formulated a concept of Vedic Maths by
deep meditation and intuition with the help of Vedas and Scriptures. He postulated sixteen sutras (formulae) and 13 sub
sutras (corollaries) of Vedic Mathematics. These sutras are easy to understand, apply and remember. With the help of
these sutras one can calculate faster than conventional maths and hence these are very much helpful in competitive exams
like MPSC, UPSC, GET, JEE, IBPS and many other.

INTRODUCTION
It is observed that many students as well as adults fear Mathematics and try to avoid it due to inefficiency in carrying out
long multiplication & division, finding square & square roots and cube & cube roots. Swami Bharati Krishna Tirtha Ji
Maharaj, 143rd Shankaracharya of Govardhan Peeth, Puri, thought deeply on this and tried to simplify these processes and
constructed 16 Sutras and 13 Sub sutras by studying ancient Indian scriptures. Swamiji wrote a book “Vedic
Mathematics”, the book and its magic effect of speedy calculations are very much pleasing. It increases speed of
calculations as well as develop interest of students in Mathematics.
OBJECTIVES OF THE STUDY:
1. To enjoy learning Mathematics.
2. To reduce difficult problems to one-line answers.
3. To overcome Maths phobia.
4. To become strong analytical thinker.
5. To improve mental ability, sharpness, creativity and self-confidence.
6. To achieve academic excellence and success in Mathematics.
The present study focused on the magical techniques in Vedic Mathematics for arithmetic division using following
1. Nikhilam Navatahscarmam Dasatah (All from nine, last from 10)
2. Paravartya Yojayet (Transpose and apply)
3. Dhwajank (Flag digit) (Using Urdhvatiryakbhyam sutra)
The conventional form of division has four terms:
(1) 𝐷𝑖𝑣𝑖𝑑𝑒𝑛𝑑 (𝐸) (2) 𝑄𝑢𝑜𝑡𝑖𝑒𝑛𝑡 (𝑄) (3) 𝐷𝑖𝑣𝑖𝑠𝑜𝑟 (𝐷) (4) 𝑅𝑒𝑚𝑎𝑖𝑛𝑑𝑒𝑟 (𝑅)
The relation between these four terms is
𝐷𝑖𝑣𝑖𝑑𝑒𝑛𝑑 (𝐸) = 𝑄𝑢𝑜𝑡𝑖𝑒𝑛𝑡 (𝑄) × 𝐷𝑖𝑣𝑖𝑠𝑜𝑟 (𝐷) + 𝑅𝑒𝑚𝑎𝑖𝑛𝑑𝑒𝑟 (𝑅)
1. Nikhilam Navatascaramam Dasatah sutra is applied when the divisor is near to the base and less than base.

Nikhilam part of divisor (modified divisor) is placed in leftmost i.e. divisor part. Then the number of digits from the right
side of the dividend equal to the number of zeros in the base are placed in the part of remainder and then remaining portion
of the dividend is placed in the middle part i.e. quotient part.
Here, division will be carried out by using modified divisor and instead of subtraction, addition will be used in Vedic
division which is found to be easier than conventional mathematics.
Algorithm to carry out Vedic Division by Nikhilam sutra:
1. Far left digit in the quotient part is considered as the first digit of quotient. Its product with the modified divisor is
added to the successive digit.
2. The result of this addition is multiplied by the modified divisor and added to next digit.
3. This process is continued up to last digit of the quotient part. The results of the addition in this part will give the
quotient. In this part at each place right most digit (the unit digit) will be placed as it is and extra digit (if exists)
will carry to the immediate left part.
4. If addition in the remainder part is greater than the divisor, then it will be again divided by the divisor and the
quotient obtained here will be added to the original quotient (obtained in quotient part) to get the final quotient
and the last remainder will be considered as the final remainder of the process.
For example: 𝟏𝟓𝟏𝟒𝟐𝟏 ÷ 𝟗𝟗
Here 99 is near to 100, so base is 100.
Deviation is calculated by applying the sutra “Nikhilam Navatascaramam Dasatah”.
Deviation: (9-9) (10-9)
Modified Divisor (M.D.): 01
Step 1: The leftmost digit 1 will be the first digit of the quotient.
Step 2: Multiply 1st quotient digit ‘1’ with M.D. (01) digit wise and resultant product digits are written in the next row
under 2nd & 3rd column of quotient part.
Addition of 2nd column digits of quotient part gives 2nd digit of quotient.
Step 3: Now multiply 2nd quotient digit ‘2’ with M.D. digit- wise and resultant product digits are written in the next row
under 3rd column in quotient part and 4th column in remainder part.

3. Ms. Neha Dattatrey Yeola / IJMTT, 67(2), 166-170, 2021
Addition of 3rd column digits of quotient part gives 3rd digit of the quotient.
Step 4: Multiply 3rd quotient digit ‘4’ with M.D. digit-wise and resultant product digits are written in the next row under
4th and 5th column in remainder part.
Addition of 4th and 5th column digits of remainder part gives the remainder.
As we reached up to the unit place digit of dividend, the job of M.D. is over.
Remainder must be non-negative number less than divisor always.
Answer: Quotient = 124, Remainder = 65
2. Paravartya Yojayet sutra is applied when the divisor is near to the base and greater than base.
In this method, obtain difference between divisor and base, then give negative sign to each digit of the difference. The
number thus obtained is called paravartya of the divisor. Now in spite of using Nikhilam use paravartya and follow the
same procedure that we have followed in Nikhilam method.
For Example: 𝟏𝟑𝟔𝟗𝟕𝟐 ÷ 𝟏𝟐𝟏
Remainder must be non-negative number less than divisor always.
Answer: Quotient = 1132, Remainder = 00
3. Dhwajank method (Flag digit): This is the universal method of division. In this method divisor is splitted into two
parts. One part i.e. left part is called as the principal divisor and the remaining part on the right side is called as
“Dhwajank”(flag digit). It is also called as flag number. Both principal divisor and dhwajank are placed in divisor part
but the division is carried out by only the principal divisor.

The arrangement is like a flag. Write principal divisor in the base part and flag digit in the above part as shown in the
following figure.
Algorithm to carry out Vedic division by Dhwajank (flag digit) method:
1. The number of digits from right side of the dividend, equal to the number of the digits of Dhwajank are placed in
the remainder part and the remaining part of the dividend is placed into the quotient part.
2. At every stage of the division, principal divisor divides the true dividend and remainder is written before the
successive digit of the dividend, which forms the gross dividend (G.D.)
3. At every stage of division, applying Urdhvatiryagbhyam sutra (vertically and crosswise) product is subtracted
from gross dividend and the result of subtraction is considered as the true dividend. Now divide the true dividend
by the principal divisor, we get the successive digit of the quotient as well as the remainder at that stage and the
process continues by placing this remainder before the next digit.
4. At any stage if Urdhvatiryag product is greater than the gross dividend, division process can’t step forward. In this
case decrease previous digit of the quotient by 1 to get the proper gross dividend for subtracting the Urdhvatiryag
product.
For example: 𝟐𝟑𝟕𝟓𝟒 ÷ 𝟕𝟒
Here we split the divisor 74 in two parts, 7 as the principal divisor and 4 as the flag digit. As there is 1 flag digit,
remainder part contains 1 digit only.
Step 1: Divide 2 by principal divisor 7, we get the quotient 0 and remainder 2.
Step 2: Place remainder 2 before next dividend digit 3, we get 23 as gross dividend. Now subtract Urdhva (vertical)
product of flag digit 4 and the first quotient digit 0 (i.e. 4 × 0 = 0), we get true dividend 23 − 0 = 23. Now divide it
by principal divisor 7, we get second digit of quotient as 3 and remainder 2.
Step 3: Place the remainder 2 before next dividend digit 7, we get 27 as gross dividend. Now subtract Urdhva product
of flag digit 4 and the second quotient digit 3, we get true dividend 27 − 12 = 15. Now dividing it by principal
divisor 7, we obtain third digit of quotient as 2 and remainder 1.

Step 4: By following same procedure as in step 2 and step 3, we get quotient as 1 and remainder 0.
Step 5: Finally subtract vertical multiplication of remainder 0 and flag digit from 4 (remainder part), we get the final
remainder as 0 and final quotient 321.
Answer: Quotient = 321, Remainder = 0
Remainder must be non-negative number less than divisor always.
CONCLUSION
The present paper gives different techniques for arithmetic division using three Vedic sutras, which provides correct and
fast solutions as compare to the method in conventional mathematics. Nikhilam and Paravartya Sutra can be applied to
limited problems i.e. when divisor is near to base whereas Dhwajank method can be applied to any divisor. These methods
make solving problems easier and interesting, that would be beneficial to those who are afraid of Maths.
