David Meredith, of San Francisco State University, had as his objective being able to solve mathematical formulas on a PC as they would be conventionally written. He achieved this objective in the 1990’s. X(PLORE) program now available on line.

 Evaluate formulas including derivatives and integrals  Graph functions in two and three variables  Perform all common matrix operations  Use the language of abstract linear algebra  Write subroutines in a powerful mathematical language

 Comments are preceded by //  Math functions: Multiply* Divide/ Add+ Subtract - Calculus Differentiatea = Dif ( f(x), x) Integrate a = In ( f(x), x =a to b)  Graph: 2D - Graph(function1, x=1 to n) 2D - Graph((function1,function2), x=1 to n) 3D – Graph3D(function1, function2, x=-1 to 1, y=-1 to 1)

 DOS  X(PLORE) for Windows 95/98/NT/2000/ME  X(PLORE) for VISTA  X(PLORE) for MAC
