Relatively Prime Numbers

This is a very simple method to find prime numbers. I use a mathematical function to find non prime numbers. Thus I have compared its efficiency with a code found on Matlab Central, Written by John D'Errico.

this is a small basic file to generate the prime numbers within a given limit, starting from 3

PrimeNumbersInformer is a small, simple, command prompt based application specially designed to help users learn the prime numbers. Once you've opened the app, just enter the limit number and PrimeNumbersInformer will create a TXT file with the prime numbers. for Windows7

This is a card game where the objective is to win tricks by forming prime numbers on the table. The game is played with composite cards: 4, 8, 10, 20, 25, 26 each with respectively 10, 4, 4, 2, 2, 2 cards and operation cards: -2, +1, +7 each with 12 cards, making a total of 60 cards. At the start...
