Bogus Proof Marathon
pifinity   7556
N 6 hours ago by NamelyOrange
Hi!
I'd like to introduce the Bogus Proof Marathon.

In this marathon, simply post a bogus proof that is middle-school level and the next person will find the error. You don't have to post the real solution :P

Use classic Marathon format:
[hide=P#]a1b2c3[/hide]
[hide=S#]a1b2c3[/hide]


Example posts:

P(x)
-----
S(x)
P(x+1)
-----
Let's go!! Just don't make it too hard!

The official Wikipedia article gives the pronounciation as /ˈrʌsɪk/ or $\boxed{\text{ruh-ssik}}$ $\blacksquare$.
