Congrats to Stick People on FTF!
If you aren't familiar with this kind of puzzle, you may want to try solving GC61BVX: (NSML02: a Micro Logic Tutorial) first. However, the puzzle is simple enough that novices may "get it" without a tutorial.
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. "B*A" represents multiplication and "BA" represents a two-digit number. So if B=6 and A=3, then BA=63 and B*A=18.
A + B = D
B * B = C
D + E = F
The geocache is hidden at N 45 04.X, W 064 26.Y, where ....
X = FBE + D and Y = CEA+C
