LiveMath™ is a computer algebra and graphing system designed for the mathematician (or mathematics student or scientist) who is not necessarily a programmer. Many of the computer algebra products available today are based upon writing a strict syntax language of programming commands and structures. Quite often, one spends more time fighting with the syntax and the requirements of the programming code than actually doing the math.
