Brumer–Stark conjecture

The Brumer–Stark Conjecture is a math problem about number theory. Number theory is a branch of mathematics that is all about working with numbers. The Brumer–Stark Conjecture states that if a number is bigger than 2 and if it can be divided evenly by lots of different numbers, then it must be a special type of number called a prime number. A prime number is a number that can be divided only by 1 and itself. Examples of prime numbers are 2, 3, 5, 7, 11, and 13.
