E to the Pi I

I used to think math was no fun,
'Cause I couldn't see how it was done.
Now Euler's my hero,
For I now see why 0
Equals e to the pi i + 1.

e raised to the pi times i,
And plus 1 leaves you nought but a sigh.
This fact amazed Euler
That genius toiler,
And still gives us pause, bye the bye.
