Beginning with simple calculations, such as the number of sheep in a herd, the field of mathematics has developed over time according to people’s needs and interests. In the course of history, mathematics has been used not only to conduct business but also to survey land and construct buildings, to analyze information and to predict phenomena. Explore the history of mathematics and learn about the contributions of both individuals and cultures to its development through these direct links on the Times Launch Point Web site:

Here are the best sites for getting your schoolwork done or for just having fun.

Level 1

Online Math Applications: History: This illustrated guide to math history introduces you to important mathematical concepts as well as innovative figures, such as Carl Gauss, who as a schoolboy could add up all the numbers from 1 to 100 in less than 10 seconds.

Ask Dr. Math (Elementary): Math History: Why does the Roman numeral D stand for 500? What is the Egyptian method of multiplication? Find out the answers to these and many other math history questions at this informative site.
