A five-day lock-in with maths the only topic of conversation would be a nightmare for many.
But for four of Whangarei's brightest boys, it's been good fun, or so they said at the end of the second day of their maths marathon.
Whangarei Boys' High School students Daniel Davis, John Ma, Nick Foulkes and Shivam Khambete are spending this week locked in the school conference room representing New Zealand in the International Mathematical Modelling Challenge. Mathematical modelling is a huge growth area that could earn them big bucks in the future, said teacher-in-charge David Moore.
"[The competition] is judged by the top people across the world in mathematics," Mr Moore said.
"For these guys to be taking part is a huge, huge deal for them, because the of way maths and economics are going towards the mathematical modelling process."
