Arrow Challenge

This is the challenge of arrow counts. You are challenging about the number of arrows that you get to the finish line and take down a number of knights with them. Each time you pass through a cover that has some mathematical operation on it like "+5, /5, or x5", the number of the arrows will change. Make sure you get some arrows at the end of the game.
