 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!

 Important Pages! Here are some pages to know before getting started to add a page on our encyclopedia of 857 pages. Getting Started Now, check out the Sieve of Eratosthenes. This helps on getting the primes on any range, e.g. a range of 100, 10 by 10. This is actually effective for primes below 10 million. Then, start contributing! Here is the first prime number, 2, for you to get started!

Question of the Day!

Hi everyone!

## Tally

The current tally is 6.

## The Question of the Day

How many times can you subtract 5 from 25? Think carefully.

## Previous Solution

Note that (3 - sqrt 5)(3 + sqrt 5)= 9-5 = 4. Thus x times (3+sqrt 5 )/2 = 1, so x+1/x = 3. Squaring both sides, we obtain the equation x^2+2+x^-2= 9. So, x^2 + x^-2 = 7. Squaring both sides again, we find that x^4+2+x^-4=49, so x^4+x^-4=47. Squaring both sids one last time, we find that x^8+2+x^-8 = 2209, so x^8+1/x^8 = 2207.

It was not an irrational number! YAY!
