Another Cost of Hyperinflation

A lesson from Zimbabwe:

Teachers reported the printing of bank notes from millions to billions and then trillions skewed their pupils' sense of numeracy, making them fail to grasp the realities of numbers.  On one geography field trip, students scoffed at being told granite rocks swept over Zimbabwe by ancient glaciers were 700 million years old. That time frame seemed insignificant.  Back then in 2008, 700 million Zimbabwe dollars bought a loaf of bread.
