Mathematics is the study of numbers, shapes and patterns. The word comes from the greek word mathema, meaning science, knowledge or learning.

Most people are probably quite familiar with the success of some branches of mathematics, such as calculus, in fields like physics. More surprisingly, the cryptographic protocols used to protect your credit card number when you transmit it over the Internet, the codes on your CDs and DVDs that correct errors on the disks without you realizing it, and the logic used inside your computer are all made possible only through the investigation of more abstract branches of mathematics like Number Theory, Linear Algebra, Abstract Algebra and Mathematical Logic.
