Climbers must Start in Kathmandu,  collecting their supplies, then Trek through the Everest Region Villages to arrive at the base of Mount Everest.

There are 5 camps on the mountain: Base Camp and 4 other camps each at a higher elevation.  These Math Puzzles are easiest on the "Trek" and in "Base Camp" and become more difficult in the higher camps.  You MUST complete the trek and lower camp puzzles to "acclimatize" yourself and get the password for the next camp.
