What are twin primes?

Twin primes are prime numbers that are just one apart, like best friends who live next door.

Think about the number line, it's like a row of houses where each house has a number on its door. Prime numbers are houses that only have two neighbors: 1 and themselves, meaning no one else can divide into them evenly. Now, imagine two prime numbers that are like best friends living in neighboring houses, they're still prime, but their doors are just one apart. Examples include (3, 5), (11, 13), or even (17, 19).

It’s like having a pair of socks, each sock is unique on its own, but together they match perfectly. Twin primes work the same way: two prime numbers that are only one apart make a special pair.

Sometimes people think about all the prime numbers as scattered dots in the number line, but twin primes are like little neighborhoods where these dots live right next to each other, it's a fun pattern hiding in math!
