One tiny illustration of how technology alters daily routines is the development of the tip calculator. Eventually, pocket calculators, websites, and smartphone apps replaced the need for handwritten computations or mental math.
There has been little change in mathematics. The ease with which people can get it has altered.
The reason modern tip calculators are successful is that they make a quick calculation which can occasionally be inconvenient almost straightforward. A few clicks can take the place of multiple steps of tedious math while dining alone, splitting a restaurant bill with others, or just comparing different gratuity rates.
The tip calculator has developed from a simple math issue to a practical digital companion for contemporary dining, from paper receipts to mobile screens.
