The film 'Good Will Hunting', if you remember, starred Matt Damon as a troubled janitor working at MIT - the twist being that he was, in fact, a secret maths genius. And how did he show this genius? By solving a highly complex maths problem chalked up on a blackboard by an MIT maths professor (Stellan Skarsgård)...

Only it turns out that that the highly complex maths problem wasn't that complex after all.

Click play on the video at the top to hear the clever James Grime from Numberphile explain why the challenge set to those MIT boffins - and solved by Matt Damon - was "a problem we can all do at home". No, really.

Honestly, next thing you know they'll be telling us that Ben Affleck didn't rescue six American hostages from Iran.
