Puzzle Description:

Euler's identity is often cited as an example of deep mathematical beauty. Three of the basic arithmetic operations occur exactly once each: addition, multiplication, and exponentiation.

It's a very pretty puzzle, but it has a few problems, mathematical and otherwise:
1. e^pi*i = -1, not 1. Euler's identity is usually expressed as e^pi*i + 1 = 0, so when you take the 1 to the other side, it has to become negative.
2. Your statement of the identity doesn't have the addition in it, which makes your "Puzzle Description" sound a little strange.

The important thing, though, is that I enjoyed solving it. That's why it's here.

Thank you for the warning. I am terribly ashamed to about the minus sign, and I corrected it. However, I will not change the equation further. There is no need for a plus sign when there is a equals sing.

Thank you. As a non-mathematician I knew about all the constants and operators here but had no idea that there was an identity linking them so elegantly. Thank you for enlightening me, plus the pretty solution.

Response to #4: Wait, solution? We're getting into chemistry now? (lol, just playing with words)

Over my head. :)

How many mathematicians does it take to change a light bulb?

-e^i*pi

:)

nice. :)

Watched a pretty cool video recently that was looking at i^i...which relates to this:

I've enjoyed the logic of your logic puzzles.

Sanane,
Your correction is good, but in your description, you say that it contains an addition. That is the problem I was alluding to. The way the - sign grows out of the black background is nice.

I can't tell you how much I miss Sanane's puzzles :(((
