   I once asked a maths teacher when his skills had ever come in handy "in real   
   life". He told me that he once had to work out how much corrugated roofing   
   would be needed to cover an outside storage area and so, rather than just   
   measuring the floor and adding a bit, he did some proper triangle geometry.   
      
   "Did it work?"   
      
   "It came out the same as if I'd just measured the floor and added a bit"
