- Microsoft Mathematics 4.0 is a scientific calculator that you can download for free. (Windows only, of course) The calculator reportedly will plot in 2-D & 3-D, help students learn to solve equations step-by-step, convert from standard to metric units, solve inequalities, and perform various matrix and vector operations.
- Web 2.0 Calc is nifty because it will not only perform many of the functions of many scientific calculators, it is also embeddable into your own personal web site or blog! You can choose from 3 styles: horizontal, vertical, or minimal, which is a basic & “non-scientific” calculator, used by non-Mathies like me!
