When I hid this, it was -15C and windy. So I was thinking "Just. One. More. Micro. Logic.". Don't worry, there will be more NSMLs.
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.
You can get the coordinates by solving the following: The nine letters (A, B, C, D, E, F, G, H, J) represent the digits from 1 to 9. 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.
ABC = DE + FG
DF = CB + HJ
EG = BD + JF
The geocache is hidden at N 45 05.X, W 064 22.Y, where ....
X = ABJ+HFG and Y = CGE – AJD.
Note subtraction in second formula. If X or Y is less than 100, put one or two "0"s in front to make a 3-digit number (e.g. "20" becomes "020"). You can check your answer below.
