Where Math Is Feared

Every year, children who question the importance of mathematics are taken on a field trip to the math-challenged Duchy of East Rosemarch.
The town square only has three sides. No two streets are the same width. The currency constantly changes value, causing economic chaos. Felons are let out of jail at random times.
Most kids realize the simple lesson of the Duchy, but there’s always a few dim bulbs that find the experience enticing and captivating.
They usually end up living in the Duchy when they get older, joining the society of math-phobic fools in perpetual numerical and geometric madness.
