In the ancient Middle East a mathematician named Al-Khwarizmi discovered algebra. Al-Khwarizmi was working in the House of Wisdom in 825 when he wrote a book called "The Book of Addition and Subtraction According to the Hindu Calculation." This book made the basic number system of 0-10. This number system is now used worldwide. Al-Khwarizmi then wrote another book called "The Compendious Book on Calculation by Completion and Balancing." This book taught algebra that we now use everyday to help discover many things.

The Middle East was one of the first places to make a major impact in medicine. The Muslim's were the first to devlope hospitals and more advanced forms of medicine. The pharmacists made medicine from plants, herbs, animals, and minerals. Doctors would use animals such as pigs to learn the body and what hapens when you do something to a part of the body. From this the Muslims devloped surgery. The medical milestones that the ancient Muslims made helped the advanced medical technology we have today.
