His book The Elements, written about 300 BC, contains many proofs in the field of geometry and algebra. This book illustrates the Greek practice of writing mathematical proofs by first clearly identifying the initial assumptions, and then reasoning from them in ... a logical way in order to obtain a desired conclusion.
