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. And when the result is too large, it will even display the results in scientific notation.

This page will calculate exact binomial probabilities for situations of the general "k out of n" type, through various applications.For example: In tossing a coin 20 times, what is the probability of ending up with exactly 16 heads among the 20 tosses?

The matrix calculator below computes inverses, eigenvalues and eigenvectors of 2 x 2, 3 x 3 and 4 x 4 matrices, multiplies a matrix and a vector, and solves the matrix-vector equation Ax = b. You can change the entries in the matrix A and vector b by clicking on them and typing.
