Welcome to the Greenbelt Mystery Series (GBMS)!  

We discovered this part of the Greenbelt while riding bike, and decided to hide as many Mystery Caches on it as we could fit with the surrounding current caches.  This section is paved and runs from Derry Street to 29th Street.  

I love Math.  The following Math calculation has two parts: first a two-digit number was multiplied by a one-digit number with a two-digit result. Then a two-digit number was added to give a two-digit result. You only use only numbers 1-9 and no number was repeated. 
 

The Problem:

    A  B

  x    C

   D   E

+ F   G

   H   J

Final Location: N 40 AG.DCG  W 076 G(J-J).(B-B)HF
