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! I am updating this very early. To Blueeighthnote: Either I stumped you, or you forgot. I hope I stumped you. I told my cousin that you were a genius, and she gave me that question to stump you. Everyone except for Imamadmad and Emmaelise401 What is the answer to the very first question of the day? What is the question of the very first question of the day? Imamadmad and Emmaelise401 The clock on Ana's bedroom wall has a minute hand of length 8 inches and an hour hand with length 6 inches. How many inches farther does the tip of the minute hand travel in a 6-hour period compared to the tip of the hour hand? Expres your answer to the nearest whole number.

Wildoneshelper: 10 points (1 achvmt pkg) 9. Emmaelise401: -- points Previous Solution Looking in the complex plane, we see that b+11i is the 60 degree rotation of a+5i. Thus: (a+5i)(cis 60) = b+11i. Equating real and imaginary parts and solving he resulting system gives a=±17/sqrt 3 and b= ±1/sqrt 3. Multiplying them results in ab=17/3. Credits to my cousin who found that question.
