This online calculator solves a system of linear algebraic equations using the Gaussian elimination method. It produces the result whether you have a unique solution, an infinite number of solutions, or no solution. It also outputs the result in floating point and fraction format.

This calculator generates a specified number of random integers within a given range.

Derives a formula from input formulas and input data to calculate remained parameters

This online calculator solves systems of linear equations using row reduction (Gaussian elimination) while retaining fractions on all calculation stages. At the end, it returns the results in two forms - as a floating point numbers and as a fractions (with numerator and denominator)

For elements with weights this calculator can filter out all combinations where total weight is under the specified limit.

This online calculator calculates probability of k success outcomes in n Bernoulli trials with given success event probability for each k from zero to n.

This article describes process of reusing another calculator's logic (algorithm) in your calculator.

This online calculator helps you find gaps and missing numbers in an integer sequence.

This calculator estimates how many circles of radius r can be placed inside another circle of radius R.

This online calculator converts angle between degrees and time units (i.e. hours).

This calculator simulates the urn (or box with colored balls) often used for probability problems, and can calculate probabilities of different events.

This online calculator calculates posterior probabilities according to Bayes’ theorem.

This online calculator calculates the mean, variance, and standard deviation of random variables entered in the form of a value-probability table.

The calculator plots entered functions on the single coordinate plane.

This calculator produces quartic equation solution using resolvent cubic.

The calculator evaluates polynomial value. The polynomial coefficients can be either real or complex.

This calculator divides one polynomial by another polynomial.

The calculator evaluates Taylor shift of the given polynomial using Shaw and Traub algorithm.

The polynomial multiplication calculator takes two univariate polynomials, each represented as a set of coefficients, and multiplies them together to generate the resulting polynomial.

This online calculator implements Newton's method (also known as the Newton–Raphson method) for finding the roots (or zeroes) of a real-valued function.
