This is a bus:
Which way is the front of the bus facing (left or right)?
A walks 10 metres in front and 10 metres to the right. Then every time turning to his left, he walks 5, 15 and 15 metres respectively. How far is he now from his starting point?
A dagger thrust at my own heart, dictates the way I'm swayed, left I stand and right I yield, to the twisting of the blade. What am I?
Moving up or right, what is the highest total you can make, using the mathematical signs along the way?
