GeoGebra

Dynamic mathematics software used for geometry, algebra and calculus
GeoGebra is a very useful  mathematics tool for education in secondary schools, which brings together geometry, algebra and calculus. GeoGebra is also a dynamic geometry system, meaning you can do constructions with points, segments, vectors, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa.

Karen's Calculator is a high-precision calculator
Karen's Calculator is a high-precision calculator. Unlike ordinary calculators, it returns completely accurate results, even with operands containing thousands of digits. If you're patient, operands and results containing hundreds of thousands of digits are possble too!

Most calculators are only accurate when dealing with numbers containing a few digits -- usually 16 to 32. When asked to calculate using larger numbers, they either fail (displaying an error) or return results that are only approximately accurate.

Karen's Calculator can easily handle numbers and results containing many thousands of digits with complete accuracy. It also includes an on-screen "tape" -- which can be saved to disk -- versatile memory features, and more!
