General purpose tools are used to gain access to a wide range of problem-solving situations and mathematical content. These tools require strategies and skills highly applicable or transferable to other technology tools being used simultaneously or in the future.

Algebra & Functions
- CAS
The Computer Algebra System (CAS) tool manipulates symbolic expressions, equations and inequalities; solves in exact and decimal forms; produces graphs and tables; expands and factors polynomials; explores parameters used in functions; slices implicitly-defined surfaces; and computes with matrices.
- Spreadsheet
The Spreadsheet tool displays and computes data stored in cells of a table; relates rows and columns by formulas; explores problems and models numerically including linear programming and Уwhat-ifФ scenarios; and produces graphs for models not easily represented by algebraic models.

Geometry & Trigonometry
The Interactive Geometry tool is a interactive geometry platform that constructs, measures, manipulates, transforms (translations, reflections, rotations, dilations) and animates geometric figures including lines, circles, angles, perpendiculars, bisectors, tangents and vectors; offers synthetic and coordinate representations of geometric objects and transformations supporting the discovery of geometric relationships and structures; supports analytic geometry using matrices; and contains a simple command-oriented programming language that supports the construction of algorithms.
- Synthetic - Construct, measure, manipulate, transform, and animate geometric figures
- Coordinate - Construct, measure, manipulate, transform, and animate geometric figures in a coordinate plane

Statistics & Probability
- DataAnalysis
The Data Analysis tool produces graphs and analysis of univariate and bivariate (categorical and quantitative) data including fitting algebraic models by-hand or Уbest-fitФ; calculates descriptive statistics; performs chi-square tests for two-way tables; and contains pre-loaded data sets that have been carefully selected to highlight centrals ideas of statistics.
- Simulation
The Simulation tool models probabilistic situations involving discrete and continuous outcomes; constructs simple and complex events with and without replacement; displays tabular and graphical results; and produces samples of varying size from distributions with an underlying probability model.

You can use this tool to create polygons and other shapes for your projects and export them to GIF images.
