c4.s3.t10.1

Śrīdharācārya's *Pāṭīgaṇita*² is a work on arithmetic and mensuration. He dealt with multiplication, division, square, cube, square-root, cube-root, fraction, rule of three and the areas of plane figures. Eight rules are given for operation involving zero but division by zero is not one of them. His method of summation of different A.P. and G.P. and solution of the problems pertaining to mixtures of things are interesting. He for the first time gave a rule to extract the root of ax²+bx=c, which is known usually as Śrīdhara’s formula.
