Little is known about his life besides is attributes to mathematics; historians aren’t even for sure where he was really born, but doesn’t matter because we know his strengths in math. The Muslim leader known as Caliph during Al-Khwarizmi’s time was al-Munan. Al-Khwarizmi was a religious man and presented two of his works dedicated to al-Munan. “These were his treatise on algebra and his treatise on astronomy.” Al-Khwarizmi studied and was a scholar at the House of Wisdom in Baghdad.

Some people have troubles comprehending what Al-Khwarizmi was saying in his al-jabr book because all the problems had to deal with real life problems; however this is what was important in those days (O’Connor). For instance, “in cases of inheritance, contracts, surveying, tax collection, legacies, partition, lawsuits, and trade, and in all their dealings with one...
