My remote control, phone and calculator has a raised dot on the number five. I was doing my accounts when i asked my wife why my calculator has a raised dot on the 5. She replied it was to help the blind work out thier bearings thus allowing them to use the calculator. thats clever i thought. then the penny dropped. how would a blind person see the answer? So why does a calculator have a dot on the 5?
