So I found this book at the library

So I found this book at the library which purports to teach you the super sekrit Japanese way of drawing by using mathematics?  But I don’t understand how this helps you draw at all.  It’s like “woman + bird = bird woman!  simple!  now draw it!”

Also, as a friend pointed out, the people on the cover look like accidental cyclopses.  And then there’s this goat lady…

I think there should also be a “- stomach” in that equation.  Forgot to carry the one.  Happens every time.
