How Vedic/Hindu Math Evolved Into What we Use Every Day - Arabic Numerals.
"The Compendious Book on Calculation by Completion and Balancing," is the great work that brought us our modern system of numerals and mathematics. Thanks to the excellent intelligence, scholarship and organizational skills of several people who perceived some of the impracticalities of the European model and its transmission, tremendous tools were compiled and made convenient, such that today, we each use these methods in some way, on a daily basis.
The decimal and the number zero are first examples of those tools.
Also was a simple method for teaching what we now call algebra, or al-jabr, which was codified by a man named Al-Khwarizmi. He was also known in Latin, as Algoritmi, the source of the word algorithm, and is the author of the above title. His fascination and skill came from studying and practicing the pattern based system known as Vedic math, which allows for rapid mental calculations based on specific principles and pattern recognition.

Though sometimes "compendious" indeed, I'm glad to have it!
