up?

Answer 5

yes its going up toward positive infinity

Answer 6

*nods*... positive integer equals to the right side pointing up... if it were -3 it would have pointed down. Similarly, if the power were even both the left and right point up, but since it's odd they have to be different... so the left side points down.
