## What is a prime number?

A prime number is a number which is only divisible by and itself.

Among mathematicians, 1 is universally regarded as non-prime.

Zero has an infinite number of factors; thus not prime or composite.

## Definition of tween primes or what are tween primes?

For a pair of primes to be Twins, they must obey the following rule.

If i and j are twin primes, then both i and j must be individually primes and also should differ by 2, i.e. (i−j) = 2 or (j−i) = 2

Examples of tween primes sets (pairs):

(101,103); (107,109); (137,139); (149,151); (179,181); (191,193); (197,199); (227,229); (239,241); (269,271); (281,283); (311,313); (347,349); (419,421); (431,433); (461,463); (521,523); (569,571); (599,601); (617,619); (641,643); (659,661); (809,811); (821,823); (827,829); (857,859); (881,883);
