You find yourself trapped in a room, with only one door to escape, and an important question to answer. You are standing on the tile marked with yellow:
How to get to the door is the main problem. You may only move exactly as many tiles as the number you are standing on, in any direction. You cannot go through a wall, and you have to reach exactly the tile the door is on. To explain this visually, if you are standing on the 2 marked below, then you could move either to the 1, 5, 4 or 3.
Additionally, you have found a cheat sheet, which may lead to the final answer. Unfortunately however, you spilled some coffee on it, which makes some of it impossible to read:
