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 2,705 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!

Link to the question! Hey everyone, This is going to get annoying, but my cousins say that this rule is going to get a lot of you people after a while: Slackers and Imamadmad Starting now until I decide to end this rule, every tenth question of the day that I divide for separate users, add five to your answer. For example, if you see questions labeled for another person to do– that means you don’t have to do it, and the question of the day is “divided” into parts. Make sure YOU keep a close tally! A number n is randomly chosen from the set {1, 2, 3, …, 24, 25}. What is the probability that the equation x2 + nx + 24 = 0 has two integer solutions? Express your answer as a common fraction. Blueeighthnote Starting now until I decide to end this rule, every tenth question of the day that I divide for separate users, add five to your answer. For example, if you see questions labeled for another person to do– that means you don’t have to do it, and the question of the day is “divided” into parts. Make sure YOU keep a close tally! The first three terms of an arithmetic sequence are p, 6, and 2p-3. What is the tenth term of this sequence (the original question had 2014th)? Previous Solution Blueeighthnote: You don't need calculus to answer the question. The two coaches start out 200 yards apart which equals 600ft. Each second the coaches get 6ft loser to each other, so it will take 100 seconds for them to reach each other. So Kim will run for 100 seconds at 20 feet pers second for a total of 2000 ft. I know I confused you. I worked it out with calculus too incorrectly, and I knew you would get around 52. Haha! Scoreboards 1. Blueeighthnote: 1680 points (2 achvmt pkgs) 2.
