Number Theory Puzzles
Playing with numbers (namely integers) can be fun, but it can also be frustrating. Some problems in Number Theory are easy to state but extremely tough to solve. The most infamous among these is Fermat's Last Theorem. So far it's solution lies outside of Number Theory. There are others which are still unsolved. One of these is Goldbach's Conjecture, which states that any integer > 2 can be expressed as a sum of 2 primes. We'll take a look at some simpler, but not doubt interesting problems.
