when was the book of numbers written in the bible
Book of Numbers The majority of modern biblical scholars believe that the Torah (the books of Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) reached its present form in the post-Exilic period (i.e., after c.520 BCE), based on pre-existing written and oral traditions and "contemporary geographical and demographic details but even more importantly from contemporary political realities".[7][8] The five books are often described as being drawn from four "sources" - schools of writers rather than individuals - the Yahwist and the Elohist (frequently treated as a single source), the Priestly source and the Deuteronomist.[9] There is ongoing dispute over the origins of the non-Priestly source(s), but it is generally agreed that the Priestly source is post-exilic.[10]
Hindu–Arabic numeral system The Hinduâ€“Arabic numeral system[1] (also called the Arabic numeral system or Hindu numeral system)[2][note 1] is a positional decimal numeral system that is the most common system for the symbolic representation of numbers in the world. It was an ancient Indian numeral system which was re-introduced in the book On the Calculation with Hindu Numerals written by the medieval-era Iranian mathematician and engineer al-Khwarizmi, whose name was latinized as Algoritmi.[note 2][3] The system later spread to medieval Europe by the High Middle Ages.
