Step 1: Flags are neat. Some flags are more common than others. All flags are queerfully colourful, but especially these uncommon ones shown here! Embark on a journey of flag-learning by matching the flag names to the correct flags.
Step 2: Each flag will be represented by one letter (the most obvious one).
Step 3: Digital roots!
Step 4: Math for some of the letters (all other letters equal what they equal as per Step 3):
A=A+2, E¹=E¹-7, E³=E³-2, I³=I³-6, L³=L³-2, N=N+1, R=R-2, S²=S²+8, S³=S³+1,
U=U-2, V¹=V¹+1
Step 5: Solve this riddle, and you'll find the final coordinates:
I got on my bike to go for a ride around town and look for the missing panda. I rode all afternoon and didn't find anything, but then I stopped in an alley where I saw something that looked like white stuffing! When I got closer to investigate, it turned out to just be crumbled chalk. Should I keep looking, or give up and come back tmrw?
O! I forgot to set the PVR to record the worm documentary for Ms. Ace! She'll be so upset. I definitely need to go back home and leave the panda hunt for another day. I quickly get back on my bike and start riding. In my franticness, I end up falling off my bike and landing in a large pile of trash. As I pick myself out of the garbage, I stumble over a large duffel bag. Curious, I look inside - a brand new Nintendo DS, with panda fingerprints! This is certainly an interesting turn of events... I should definitely take this to the lab for further identification right away, and forget about recording that documentary. Guess I'll have to face the worst of Ms. Ace's wrath after all!
