On Line Calculators for Every Need

MathPortal.org has an enormous number of calculators for any algebra or geometry need. Polynomials--factoring, solving equations, adding, multiplying, you name it. Rational equations, radical equations, quadratic equations, they've got those too.

Since you cannot use the calculators on tests, they are not a replacement for solving the problem yourself, but they can confirm an answer you are not sure about. They also provide step-by-step solutions for those problems you simply cannot understand.

 Use only when necessary; do not become too dependent on them.  Check the calculators here.
