Alpertron Calculators

Number Theory, Polynomials and Recreational Math

This app offers 10 very fast calculators: Solving Discrete Logarithms, Factoring Integers, Factoring and Roots of Integer Polynomials, Quadratic Equations in Integers, Modular Quadratic Equations, Sum of Four Squares, Sum of Four Cubes, Sum of Two Squares and Power, Factoring Gaussian Integers and Continued Fractions.

All calculators support 10,000 digits. Some support 100,000 digits.

Each calculator includes help that indicates how to operate it and also a theoretical introduction to understand how it works.

The polynomial factorization and root solver calculator and the quadratic equations in integers have a step-by-step mode that shows how the solutions are found.

Most calculators have a batch mode that enables the user to find several solutions just by pressing a button. The integer factorization calculator has also a programming mode using the Blockly visual language.
