Geocache Description:

The cache is not at the coordinates posted above, but is located no more than one or two miles away. You must solve the puzzle below to determine the correct location for this cache.


Several years ago, a math teacher showed me how a few simple equations could be used to "prove" that one equals two:


1. y = x
2. y * x = x2
3. y * x - y2 = x2 - y2
4. y * (x - y) = (x + y) * (x - y)
5. y = (x + y)
6. y = y + y
7. 1 = 2

Can you spot the mistake?

Please be careful to replace the cache exactly as you find it.



You can validate your puzzle solution with certitude.
