Oh, perfect numbers are like little treasures in the world of math! Up to 100, we have two perfect numbers: 6 and 28. A perfect number is when all its divisors (except itself) add up to the number, creating a harmonious balance in the mathematical universe. Just like adding a happy little tree to a painting, perfect numbers bring a sense of symmetry and beauty to the world of numbers.
