Euler Returns

David Slauenwhite brings another mathematically significant roadsign from the RSM-leading state of Massachusetts. This roadsign qualifies not only with mathematical significant, but Mr. Slaeunwhite notes that it actually has an error in it as well. South 202, referenced in the sign, is actually Route 122 North, which eventually meets 202 but not for a couple of miles!



Mr. Slauenwhite gives us Euler through some complicated mathematical gymnastics.

$${{202 + 122 + {{26}\over{13}}} \over {5!}} \rightarrow {{326}\over{120}} \approx 2.716666 \approx e$$

This sign is on Route 21 in Massachusetts, now known merely as South Athol Road, as it meets Route 122.
