What are all the twin primes less than 30?
The twin primes less than 30 are (3, 5), (5, 7), (11, 13), (17, 19), and (29, 31). Twin primes are pairs of prime numbers that differ by two. Notably, while 29 is prime, its twin 31 exceeds 30, so the valid pairs below 30 are limited to the first four. Therefore, the twin prime pairs less than 30 are (3, 5), (5, 7), (11, 13), and (17, 19).
