Nobody invented them - they are a characteristic of the set of numbers.
41 and 43 are twin prime numbers. Twin primes are a set of two prime numbers that differ from each other by two. Here are the sets of twin primes less than 100: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
It is the set {2}.

A set of anything usually means more than one. Twin primes are a set of two prime numbers that differs from each other by two. Here are the sets of twin primes less than 100: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

A twin prime is a prime numberthat differs from another prime number by two. The first few twin primes are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
74 is not a prime number. No even number greater than 2 is prime. Twin primes are a set of two prime numbers that differ from each other by two. Here are the sets of twin primes less than 100: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

The larger number of the fourth set of twin primes is 19.
0.2 is not a prime number. Prime numbers belong to the set of whole numbers.

A number is relatively prime to another number or set of numbers when their GCF is 1.
A set of anything usually means more than one. Twin primes are a set of two prime numbers that differs from each other by two. Here are the sets of twin primes less than 100: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
The 20th prime is 71.
