53 + 47 = 100 : simples? But those itching for their Good Will Hunting moment, the Guinness Book of Records puts Goldbach’s Conjecture as the current longest-standing maths problem, which has been around for 257 years. It states that every even number is the sum of two prime numbers: for example, 53 + 47 = 100.

**What is the only math problem that Cannot be solved?**

The Collatz conjecture is one of the most famous unsolved mathematical problems, because it’s so simple, you can explain it to a primary-school-aged kid, and they’ll probably be intrigued enough to try and find the answer for themselves. So here’s how it goes: pick a number, any number. If it’s even, divide it by 2.

#### What is the easiest math problem ever?

If by ‘simplest’ you mean easiest to explain, then it’s arguably the so-called ‘Twin Prime Conjecture’. Even schoolchildren can understand it, but proving it has so far defeated the world’s best mathematicians. Prime numbers are the building blocks from which every whole number can be made.
