Tha coordinates above are a convenient place to park.
The grid below has a numerical sequence in each column and row.
Fill in the blank squares to calculate the cache location using the following formulae.
N AA BB.CCC W DD EE.FFF
AA= I1 + H2
BB= (F3(C9-F5)/(B7+A3)+C5-D4)
CCC= A9+C7
DD= G1+H2+B7-C4-E2
EE= C5/(B7/I4)
FFF= C9+D6+B2+G9+F2-A3+B8
