Polynomial Expressions

Algebra -- "Quickmath can expand, factor or simplify virtually any expression, cancel common factors within fractions, split fractions up into smaller ('partial') fractions and join two or more fractions together into a single fraction."

Solving Equations

Equations -- "The equations section of QuickMath allows you to solve and plot virtually any equation or system of equations."
Solving for 2 Unknowns -- Solve two equations in two unknowns.
Solving for 3 Unknowns -- Solve three equations in three unknowns.
Linear Equation Solver -- Solve three equations in three unknowns.
4 Unknown Calculator -- Solve four equations in four unknowns.
Quadratic Equation Calculator -- Enter the parameters a, b, and c of the quadratic equation and solve for x.
Cubic Equation Calculator -- Solve an equation in the form AX^3 + BX^2 + CX + D = 0.
Inequalities -- "The inequalities section of QuickMath allows you to solve virtually any inequality or system of inequalities in a single variable."

Matrix Algebra

Matrices -- "The matrices section of QuickMath allows you to perform arithmetic operations on matrices. Currently you can add or subtract matrices, multiply two matrices, multiply a matrix by a scalar and raise a matrix to any power."
Linear Algebra Matrix Calculators -- Includes a (1) matrix calculator which "lets you calculate the determinant, adjoint, inverse, transpose, and more of a 'n x n' matrix", (2) a linear algebra calculator which "has the ability to calculate the determinant, adjoint, and inverse of a '3 x 3' matrix", and (3) a linear system of 3 equations which "can solve a linear system of 3 equations and 3 unknowns".

Plotting Functions and Equations

Graphs: Equations -- Plot equation in terms of the variables x and y.
Graphs: Inequalities -- Plot polynomial inequality in terms of the variables x and y.
Tracés animés -- "Tracés animés allows you to plot curves and surfaces,in 2D or 3D, which zooms, deforms and/or rotates in all directions."

Factorials

Exponents and Logarithms

Exponential Expression Calculator -- "This JavaScript Calculator will find the product of an exponential expression (as in x raised to the power of y, where y is less than 600). It will handle positive and negative exponents and positive and negative bases."
A simple Logarithm Calculator -- Enter two parameters in the equation b^x=y and compute the appropriate third value. Read the instructions to see how to use the calculator.

Resources and Interactive Exercises

Practical Algebra Lessons -- "The following lessons give practical tips, hints, and examples, and point out common mistakes." Includes topics on numbers, beginning algebra, intermediate algebra, advanced algebra, solving word problems.
Algebra Help and Tutorials -- links to "Algebra tutorials, instructions, interactive lessons and information to help enhance algebraic learning and thinking."
Math2.org -- Theorems, tables, identities, proofs and graphs for general math, algebra, geometry, trig, linear algebra, discrete math, statistics, calculus, and advanced topics.
