One explanation for this used to be sociological: decimal numbers have been thought of for a very long time as symbols of the evil Muslim foe. yet there has been a extra vital functional cause of the lengthy hold up. for many reasons in lifestyle, Roman numerals proved sufficient and it used to be purely with the rising curiosity in technological know-how throughout the Renaissance that the significance of arithmetic used to be understood and numbers liked as being on the middle of arithmetic, and for that reason the very beginning of contemporary technological know-how. The Hindu-Arabic numbering method was once ultimately popularized in Europe through the nice mathematician Leonardo of Pisa (Fibonacci) (c. 1170–1250), who had travelled in the course of the Mediterranean international to check lower than the best Arabic mathematicians of the time. He again from his travels round the 12 months 1200 and inside a few years, elderly 32, wrote what he had learnt within the Liber Abaci (Book of Abacus, or ebook of Calculation). although, the historian George Sarton makes the subsequent element: ‘A unmarried instance will suffice to point the slowness of the combination of Hindu numerals in Western utilization.
