Welcome to the Prime Numbers Wiki!

Welcome to Prime Numbers Wiki! In this wiki, we will post all the prime numbers that are in a range of 100. Here, we can even post videos of our own, summarizing the page, e.g. showing the prime numbers on 1-100, the difference between prime and composite numbers, and many more about the topic. Even the Sieve of Eratosthenes will help us show the correct way of showing primes. Come, join now! Making links will be a great way to show the proof of why it is prime; just give a subjective detail of the number, e.g. this number is prime because it is not divisible by 2, then show the answer. Dead-end links will make our wiki a rotten one, so please add some links to those numbers. We can even make a bunch of pages!
