What’s inside
All 13 chapters, the famous riddles, and the methods behind them.
Every solution shows two things side by side: Bhaskara’s original approach and the modern method.
The 13 chapters
- Definitions and basic operations, fractions, zero and negative numbers
- Square and cube roots
- Arithmetic and geometric progressions
- Plane and solid geometry, and the shadow of the gnomon
- Combinations and permutations
The famous problems
- The Beautiful Maiden’s Riddle
- The Peacock and the Snake
- The Bees and the Lotus
- The Broken Bamboo
- 11 word problems in all, each solved step by step
The methods
- The Rule of Three
- The Kuttaka (pulverizer) for indeterminate equations
- Bhaskara’s treatment of surds
- The Chakravala method for Pell’s equation, centuries before the European solutions
The context
- Bhaskara’s early work on differential calculus concepts
- Comparison with Greek and Chinese mathematical traditions
- A timeline of Indian mathematics, from the Sulba Sutras to Ramanujan
All 13 chapters carry detailed commentary, not just restated formulas.

Questions readers ask
Asked before downloading, answered straight.
Is it actually free?
Yes. There’s no payment anywhere in the flow. The checkout creates your order and your download link instantly.
Do I need Sanskrit or a history background?
No. Everything is reconstructed in modern notation, and each famous problem is solved step by step, showing Bhaskara’s original approach next to the modern method.
Is this a history book or a mathematics book?
Mathematics first. The context is there, a comparison with Greek and Chinese traditions and a timeline from the Sulba Sutras to Ramanujan, but the core of the book is working through the problems and the methods.
What is the Chakravala method?
Bhaskara’s method for solving Pell’s equation, and it predates the European solutions by several centuries. The book covers it alongside the Kuttaka algorithm for indeterminate equations.
Why is there a checkout for a free PDF?
The download is delivered through my store rather than a raw file link. The free checkout creates your download link instantly, with no payment details anywhere.
What I’m not going to claim
There are no ratings to show you. It’s a free PDF, and I’d rather be plain about that than decorate the page.
This is a reconstruction in modern notation, not a scholarly translation of the Sanskrit. If you want philology, you need a different book. If you want to actually solve the problems, this is the version you can work through.
And it stays with the Lilavati. Bhaskara wrote more than this one text, and the book doesn’t try to cover the rest.
Hey, I’m Gaurav 👋
I taught mathematics before I built websites, and the Lilavati problems were my answer whenever a student decided math was joyless. Bhaskara asks about bees, peacocks, and broken bamboo, and somewhere in the middle of the story you’re doing real mathematics.
