# Twin Primes Calculator, 1- 100 Twin Primes, Definition Of Twin Primes

## What Are Twin Primes?

First let's briefly review the definition of a Prime Number. A Prime Number is a Natural Number that has exactly two positive divisors, the number one (1) and the number itself. Prime numbers starts at the number two (2) and continues to infinity. Example: 2, 3, 5, 7, 11, 13, 17, 19, 23, ... infinity.

**Twin Primes** are two Prime Numbers that differ
by two. For example, here are the first four sets of twin primes: {3, 5}, {5, 7},
{11, 13}, and {17, 19}. As you can see, all the numbers are prime and differ by
a value of two. Mathematicians believe but have yet to prove there are an infinite
number of Twin Primes. The Twin Primes calculator
below can display up to the first 100 Twin Primes.
