Huhhh?
Just a simple fun math diversion today that I've adapted from another blog:
-- Proof --
Suppose:
a + b = c.
This can then be equivalently written as:
(4a – 3a) + (4b – 3b) = 4c – 3c
After reorganizing (adding/subtracting from both sides):
4a + 4b – 4c = 3a + 3b – 3c
Take the constants out of the brackets:
4(a + b – c) = 3(a + b – c)
Remove the same term left and right:
4 = 3
Ta-daaaaaaa!!

Stop it! You're making my brain hurt!
Had a couple of emails from people frustrated at finding the flaw in the 'proof,' so for any hurting brains out there, the answer below:

==> since a+b=c, a+b-c must equal 0. This means in the very last step of dividing out a+b-c you are dividing by 0 -- A math NO-NO! (or alternatively you can say that 4x0 does equal 3x0).
