**Summary:**
Here are some external math pages that are worth checking
out. Each of this deals with multiple fields of math. You’ll also find
more specialized pages linked from the index pages for
Algebra,
Trig,
Statistics,
Calculus, and
Student/Faculty.

- Mathworld,
formerly Eric’s
Treasure Trove of Mathematics, is an excellent starting point when
you need the
**definition of a math term**, or a fast introduction to an unfamiliar concept. - S.O.S. Mathematics offers a lot of review questions (with solutions) from algebra to differential equations. There’s also a set of message boards (registration required).

- The
MacTutor History of Mathematics Archive
is just what its name implies. It’s a good
supplement to Eric’s Treasure Trove for
**historical topics**. Two specialty pages try to track down the earliest uses of some mathematical symbols and some words of mathematics.

- Euler Math Toolbox
is a freeware numerical lab with real and complex numbers, functions,
graphs, vectors, matrices, symbolic algebra—“not a
**MatLab clone**, but very similar to this program”. It’s a free download to your computer.

- QuickMath has stepped into the niche left vacant by the demise of Vanderbilt’s MathServ Calculus Toolkit. QuickMath can integrate, differentiate, solve equations and systems of equations, and more.
- Calculator.net has a bunch of math calculators, including a triangle solver.
