Theorem: e=1
Proof:
2*e = f
2^(2*pi*i)e^(2*pi*i) = f^(2*pi*i)
e^(2*pi*i) = 1
Therefore:
2^(2*pi*i) = f^(2*pi*i)
2=f
Thus:
e=1

proof by example:
The author gives only the case n = 2 and suggests that it contains most of the ideas of the general proof.
proof by intimidation:
"Trivial."
proof by vigorous handwaving:
Works well in a classroom or seminar setting.
proof by cumbersome notation:
Best done with access to at least four alphabets and special symbols.
proof by exhaustion:
An issue or two of a journal devoted to your proof is useful.
proof by omission:
"The reader may easily supply the details"
"The other 253 cases are analogous"
"..."
proof by obfuscation:
A long plotless sequence of true and/or meaningless syntactically related statements.
proof by wishful citation:
The author cites the negation, converse, or generalization of a theorem from the literature to support his claims.
proof by funding:
How could three different government agencies be wrong?

Clearly: I don't want to write down all the "in-between" steps.
Trivial: If I have to show you how to do this, you're in the wrong class.
It can easily be shown: No more than four hours are needed to prove it.
Check for yourself: This is the boring part of the proof, so you can do it on your own time.
Hint: The hardest of several possible ways to do a proof.
Brute force: Four special cases, three counting arguments and two long inductions.
Elegant proof: Requires no previous knowledge of the subject matter and is less than ten lines long.
Similarly: At least one line of the proof of this case is the same as before.
Two line proof: I'll leave out everything but the conclusion, you can't question' em if you can't see' em.
Briefly: I'm running out of time, so I'll just write and talk faster.
Proceed formally: Manipulate symbols by the rules without any hint of their true meaning.
Proof omitted: Trust me, It's true.

First and above all he was a logician. At least thirty-five years of the half-century or so of his existence had been devoted exclusively to proving that two and two always equal four, except in unusual cases, where they equal three or five, as the case may be. - Jacques Futrelle, "The Problem of Cell 13"Most mathematicians are familiar with - or have at least seen references in the literature to - the equation 2 + 2 = 4. However, the less well known equation 2 + 2 = 5 also has a rich, complex history behind it. Like any other complex quantitiy, this history has a real part and an imaginary part; we shall deal exclusively with the latter here.Many cultures, in their early mathematical development, discovered the equation 2 + 2 = 5. For example, consider the Bolb tribe, descended from the Incas of South America. The Bolbs counted by tying knots in ropes. They quickly realized that when a 2-knot rope is put together with another 2-knot rope, a 5-knot rope results.Recent more...
