I really liked the concept and location of GC6W6J2 (Cachers from the World - Come Together), but that's archived now unfortunately. Hopefully with this cache, this location will continue to have a cache albeit in a simple multi-cache form. So without further ado,
Welcome to the Marina Bay Waterfront Promenade!
Other than the floating Apple Store and the restaurants and bars, you may have also noticed that there are some unique trees lining the promenade. Walk amidst the trees, and you would have found out that these trees were planted in 2010 - to commemorate the inaugural Youth Olympic Games (YOG) in Singapore! Each tree was planted to symbolise each participating country in the YOG. This was indeed a coming together of cultures, nations and people, all for one common purpose of achieving sporting greatness.

International Olympic Committee (IOC) President, Dr Jacques Rogge symbolically shovels soil during a Youth Olympic Games tree dedication ceremony at Marina Bay Waterfront Promenade.
To find the cache, you first need to find out the answers to these questions. Some of these answers can be found online as well:
1. How many trees were planted? This includes all trees and not just the ones at the published coordinates. You should come up with a three digit number. Let the first digit be A.
2. Each tree has a plaque, stating which country that specific tree is dedicated to. How many words are there in the third line of the plaque? The third line is the same regardless of which plaque you look at (starts with 'to' and ends with '2010'). Let the number of words be B.
3. Who was the Minister for Community Development, Youth and Sports at the time of the YOG? Let the number of letters in his first name be C.
Once you have collected all 3 answers, you may find the final cache at:
N 01° 17. (A-1) (B/2) (B-C-1)
E 103° 51. (B-3) (C/2) (2A + C - 1)
