If you aren't familiar with this kind of puzzle, you may want to try solving GC61BVX: (NSML02: a Micro Logic Tutorial) first, or try NSML08, another easy one.
This particular puzzle is one of the easier micro logics. To get to the final, you can go under the highway by following the tunnel near the parking coordinates (see "Tunnel Vision" cache for details).
You can get the coordinates by solving the following: The six letters (A, B, C, D, E, F) represent the digits from 1 to 6. No two letters are equal. "D*A" represents multiplication and "DA" represents a two-digit number. So if D=2 and A=3, then DA=23 and D*A=6.
B * C = C
A * D = EA
F - C = E
The geocache is hidden at N 45 03.X, W 064 26.Y, where ....
X = ADE and Y = DFB + CAD
