TULSI-PRAJÑA, Oct.-Dec., 1992
(2) Vyavahara-subjects of treatment,
(3) Rajju-geometry.
(4) Rāsī-mensuration of solid bodies, (5) Kālasavarṇa-fractions,
(6) Yavattavat simple equations
(7) Varga-quadratic equations
(8) Ghana-cubic equations
(9) Vargāvarga-biquadratic equations,
(10) Vikalp-permutations and combinations.
This interpretation is difficult to reconcile with some other aspects of Indian Mathematics. For instance there is very little Indian Mathematics of even later periods relating to cubic and biquadratic equation. On the other hand it is ture that Jaina Mathematics has been interested in permutations and combinations. Also the Jaina interest in very large numbers for their measurement of space and time would suggest that their programme would include some reference to high powers of numbers. In the light of such contextual knowledge, Srinivās iyngar (1967) has an interpretation. I accept his interpretations with a few minor n odification.
The resulting list of the topics is as follows:
(1) Parikarma-the four fundamental operations of arithmetic viz, addition, substraction, multiplication and division. (2) Vyavahāra-the applications of arithmetic to concrete pro
blems.
(3) Rajju-plane geometry calculations, as carried out by means of a rope.
(4) Rāsī-heap and hence it may refer to measurements of grain etc., that is mensuration of plane figures and slids.
(5) Kālas varṇa-fractions,
(6) Yavattavat-sinceya () stands for the unknown quantity, this topic may be interpreted as the study of "that which is unknown"; it is the science of algebra in however a rudimentary form it may have existed; simple summations are part of this topic.
(7) Varga-may be an abbreviation for square as well as square
root.
(8) Ghana-may be an abbreviation for cube and cube-root. (9) Vargāvarga-may be abbreviation for higher powers and
