Get one half by squaring (Posted on 2004-09-20) Difficulty: 4 of 5
Can you solve the following equation?

= 1/x + 1/y +...+ 1/z

All variables must be different, positive integers, and there must be a finite number of terms.

That's really nice.  How'd you find that? 

I still think that the way to solve this is by number theory rather than by inequalities.
