The NUMBERS calculator is designed to facilitate the computation of number theoretic functions for positive integers of up to 150 decimal digits on almost any PC. The author's main objective in writing NUMBERS was to allow students in a course in elementary number theory to do nontrivial examples and pursue investigative projects. Included operations are finding gcds, lcms, mod arithmetic, quadratic residue test, Chinese remainder systems, number of divisors, sum of divisors various pseudoprime tests, continued and Farey fractions, Fibonacci numbers, Lucas numbers, encryption and decryption, etc.

A collection of object files which can be linked into a Turbo Pascal program are provided.
