Al-Khwarizmi was a Persian mathematician, astronomer, astrologer and geographer whose contributions in these areas provided the foundation for later innovations in algebra and trigonometry. He is considered by many the inventor of algebra.rnOne of Al-Khwarizmi's major works was a treaty he wrote in 825 AD on Hindi numerals, which was translated into Latin by the Toledo School in Spain during the 12th century, titled Algoritmi de numero Indorum. This book explained for the first time in the Occidental world the simplicity of the Hindu mathematical calculation, which contributed to the birth of today's algorithmic calculus. His work substituted long and tedious mathematical demonstration with graphs or charts.rnNowadays, the use of algorithms in the financial community is extensive and dates at least to S. Kaplan's "Computer Algorithms for Finding Exact Rates of Return" (The Journal of Business, October 1967), which improved the methodology used by Lawrence Fisher when calculating simple investment rate of returns.
