C. ) according to the powers of unknown quantity e.g. \*yāvat-tāvat\* ( simple ), \*varga\* ( quadratic ), \*ghana\* ( cubic ), \*varga-varga\* ( biquadratic ) etc. But such classification was not maintained. Brahmagupta ( 628 A. D. ) gave the following classifications : ( 1 ) \*eka-varṇa samīkaraṇa\*—equations in one unknown comprising linear and quadratic equations, ( ii ) \*aneka-varṇa samīkaraṇa\*— equations in many unknowns, ( iii ) \*bhāvita\* — equations involving products of unknown. This classification received further elaboration at the hands of Pṛthūdakāsvāmī ( 860 A. D. ) and Bhāskara II ( 1150 A. D. ). - [Previous: c7.5](https://indike.org/pramana/ins.science.bag-1979.c7.5) - [Next: c7.7](https://indike.org/pramana/ins.science.bag-1979.c7.7) - [Up: c7](https://indike.org/pramana/ins.science.bag-1979.c7) ## Cites (1) - [Ṭhāṇaṃga](https://indike.org/pramana/in.jaina.sveta.anga.3) — Sudharman, Ardhamāgadhī Prakrit --- Source: [https://indike.org/pramana/ins.science.bag-1979.c7.6](https://indike.org/pramana/ins.science.bag-1979.c7.6) · Pramāṇa
