Indian mathematician Bashgaro wrote a math book, Anabel Watty. What is the story background of the topic?

"Anabel Watty" means "beautiful", which is said to be the name of Pashgaro's daughter. At the beginning, a prophet said that she would never get married, and Pashgaro was also an astrologer, so he also predicted his daughter's good day. He put a cup in the water, and there was a small hole in the bottom of the cup. Water slowly enters the cup through the small hole. A sinking glass is his daughter's lucky day.

His daughter may be in a hurry, so she ran to see when the cup would sink. Unexpectedly, a bead slipped from the jewelry and fell into the cup, which just blocked the hole. Because water no longer entered the cup, the cup could not sink.

So "Anabel Vatti" is doomed to never get married. To comfort her daughter, Puska named the book after her, saying: Your name will remain immortal with this book. In Anabel Watty, Pashgaro mainly expounds the definitions of some names and terms, arithmetic operation rules, the application of interest rates, arithmetic and geometric sequence problems, plane and solid geometry, algebra problems and combination problems.

About the author:

Indian mathematician and astronomer Bashgaro. He was born in Jabir, Mysore, and worked in Ujain for a long time. 1 150 years, he wrote an almanac, which is divided into four chapters: applied problems, algebra, celestial sphere and planetary mathematics.

In the book, he comprehensively and systematically introduced the knowledge of arithmetic, algebra and geometry, reflected the notation of India in the12nd century, recorded eight basic operations of natural numbers, fractions and negative numbers, collected various mathematical problems related to social and economic activities such as interest, commodity exchange, alloy composition, earthwork, warehouse volume and water conservancy construction, and gave some achievements in algebra, geometry and trigonometry.
