He flourished under the Buwayhid sultan Majd al-dowleh, who died in 1029-30AD, and under his successor. He wrote a book on arithmetic in Persian, and then Arabic, entitled the "Satisfying (or Convincing) on Hindu Calculation" (''al-muqni fi-l-hisab al hindi''). He also wrote on Archimedes 's Lemma ta and Menelaus's Theorem (''Kitab al-ishba'', or "satiation"). where he made corrections to ''The Lemmata'' as translated into Arabic by Thabit Ibn Qurra , which was last revised by Nasir Al-Din Al-Tusi . Nasawi's arithmetic explains the division of fractions and the extraction of square and cubic roots (square root of 57,342; cubic root of 3, 652, 296) almost in the modern manner. It is remarkable that al-Nasawi replaces Sexagesimal by decimal fractions. Source #2 given below also gives an analysis of a mid-12th century manuscript in which a summary of Euclid 's Elements exists by al-Nasawi. He is thought to have died in about 1075 A.D. in Baghdad , Iraq .
