Benjamin Banneker, a self-taught mathematician, surveyor and astronomer published annual almanacs containing his astronomical observations and predictions. Banneker who also used logarithms to apply the Law of Sines believed that the method used to solve a mathematical problem depends on the tools available.

The four puzzles of scientist Benjamin Banneker are mentioned. These puzzles are of historical interest and demonstrate the ways that available technology can be used to efficiently explore and solve problems.

Using computer algebra systems (CASs) in solving traditional algebra and calculus problems by students is advocated, by illustrating five provocative axioms and examples. The advantage of using CASs as powerful tool in teaching mathematics is analyzed.

The software package 'GraphExplorer: Function Graphing Software' is recommended for its usefulness to most high school students and teachers, and its easy usage. Its capabilities include the partitioning of graphs, the combination of equations, Riemann-sum features for calculus, and various graphing scenarios. However, this Macintosh-intended program could be more user-friendly, as exemplified by often slow graphing, a lack of help screens, limitations with inequalities and an inability to graph functions simultaneously. The software package is prized at $99.95.
