Question: how much is 13 plus 11?

please help.

They're trying to trick you into thinking that one's a difficult numerical question involving tracking down the parents of the xi in the error term, and then fitting a spline to something or other. Don't fall for it. What 13 + 11 is, is a pictorial representation of breast reduction surgery viewed from above (Before and after). The obvious answer, once you've become aware of this, is -2.

You can prove the veracity of this by examining the letter b from various points of view. Obviously we now know what B stands for, right? So the what do you get from the letter "b" ? Side view, right?

So then the word "Boob" has a certain perfect symmetry, doesn't it?

Sounds like the studying isn't going so well then Rotti...
