x-y ≠ -y+x ?

Did the pizza I had for dinner tonight cancel out my run, or did my run cancel out the pizza? And why is it that, even though I know it's the same thing, I really, really really want the second answer to be the correct one? The overall calorie count is the same way, but the thought of that work being undone causes marked anxiety, while the thought of guilt-free pizza is incredibly appealing.

Why?
