Brahmagupta (born 598 AD)
Wrote Brahmasphuta Siddhanta:– Zero
0 0 = 0 ?
A 0 = 0 ?
– Pythagorean triples:
“The height of a mountain multiplied by a given multiplier is the distance to a city; it is not erased. When it is divided by the multiplier increased by two it is the leap of one of the two who make the same journey”

First known solution of quadratic equations:
“Diminish by the middle [number] the square-root of the rupas multiplied by four times the square and increased by the square of the middle [number]; divide the remainder by twice the square. [The result is] the middle [number].
Whatever is the square-root of the rupas multiplied by the square [and] increased by the square of half the unknown, diminish that by half the unknown [and] divide [the remainder] by its square. [The result is] the unknown.”
From Chapter 18, Brahmasphuta Siddhanta

SUTRA TRANSLATION
1 Ekadhikina Purvena By one more than the one before
2 Nikhilam Navatashcaramam Dashatah All from 9 and the last from 10
3 Urdhva Tiryagbyham Vertically and crosswise
4 Paraavartya Yojayet Transpose and adjust
5 Shunyam Saamyasamuccaye When the sum is the same that sum is zero
6 Anurupye Shunyamanyat If one is in ratio, the other is zero
7 Sankalana Vyavakalanabhyam By addition and subtraction
8 Puranapuranabyham By the completion or non-completion
9 Chalana Kalanabyham Differences and similarities
10 Yaavadunam Whatever the extent of its deficiency
11 Vyashtisamanstih Part and whole
12 Shesanyankena Charamena The remainders by the last digit
13 Sopaantyadvayamantyam The ultimate and twice the penultimate
14 Ekanyunena Purvena By one less than the previous one
15 Gunitasamuchyah The product of the sum is equal to the sum of the product
16 Gunakasamuchyah The factors of the sum is equal to the sum of the factors
Ekadhikina Purvena:one more than the one before
example: calculating 1/191 (one more than the one before: 2)21421842168421 (carry 1)368421 (carry 1)7368421 47368421 947368421… 052631578947368421Eighteen digits (denominator - numerator) so STOP
Hence 1/19 = 0.052631578947368421 recurring
Nikhilam Navatashcaramam Dashatah: All from 9 and the last from 10
• Used for long calculations quickly:
Example: 10000 - 4679
9 - 4 = 5
9 - 6 = 3
9 - 7 = 2
10 - 9= 1
So 10000 - 4679 = 5321
Applications of Vedic Maths: EDUCATION
easier than conventional arithmetic?
Maharashi School, Lancashire:“livelier classes, greater student enjoyment and
understanding, and increased academic performance”
(Mark Gaskell, 2000)
Average GCSE maths scores of over 80% all taken a year early.
Enthusiasm and interest!
