Yaay, Tim Hunkin. I really miss his stuff from the Observer days.

Never seen the second one. Nice.

Second panel is wrong. We more of the actual proofs on how 0.999... = 1.

Fallacious proofs are always fun, but I can't approve of the second panel's inaccurate explanation.

The second panel's explanation is incorrect. At no point in the proof does the author take the square root of (2 - 5/2)! The reason is that each square root has a positive and a negative root and the incorrect one is used. It is much more simply stated as "sqrt((-1)(-1)) = sqrt((1)(1)), therefore -1 = 1". If you take the negative of 3 - 5/2, you get 2 - 5/2. That's not a coincidence.

Unnecessarily done via comic format.

Fun math stuff.

Simple math 'proofs' of impossible things with quick explanations of why they are not actually true.

The way to prove 1=2 and 2=3. The problems are easy to spot, though.

1=2!!!

Yup, oldie, but a goodie!

As has been alluded to by other comments, the explanation for Panel 2 is incorrect. Taking the square root of both sides is a valid operation, but the next to last line should read

±(2-5/2) = ±(3-5/2).

In other words, ±1/2 = ±1/2.
