The answers are really funny but the question isn't really about mathematics. Would it be hypocritical to upvote all the answers and vote to close the question? :) – Rahul Narain Jan 27 '12 at 21:15

If we can move one "character", then moving the horizontal line over gives $62=63-1$ – The Chaz 2.0 Jan 27 '12 at 13:58
@TheChaz, please post it as an answer so I can +1 it. That's so damn good it made my Day already! (it is 6am here) – Arjang Jan 27 '12 at 19:41

(By request...)

If we can move one "character", then moving the horizontal line over gives $62 = 63 - 1$

+1, this answer needs a better question! – Arjang Jan 27 '12 at 20:20

$6263 \neq 1$.

I moved one character not a digit :)
