Simple mathematic calculations have no doubt been used since early man began to trade. Five thousand years ago, early Babylonians and Egyptians began using more complex mathematical formulas in their observations of the stars and construction of buildings. The Ancient Greeks are credited with beginning a systematic study of mathematics and since then, the scope of mathematics has only continued to expand. Although it may seem that all there is to know about math has already been discovered, in fact, new theorems and proofs add to our knowledge each year. As such, for anyone zealous enough to pursue math beyond its basic principles, it promises to be an exciting and rewarding field. Introductory coursework in mathematics must be completed in the following order: College Algebra, Trigonometry, Analytic Geometry.
