Find the answers to these questions, and reduce them to a single number (see below) and call those numbers A, B, C and D. The cache can be found at:
N 51 Y W 000 X
Where:
1000X=A⁵D²-C³-B³-D
1000Y=A²CD³+C³+BC
To reduce the answers to a single number:
- First remove any non-alphanumeric characters so IJ K-5 becomes IJK5
- Convert any letters to their numeric equivalents, so IJK5 becomes 910115.
- Next sum the individual digits: 9+1+0+1+1+5=17
- Repeat step 3 until you have a single digit remaining: 1+7=8
