I can LaTeX!
Post some TeX proofs of cool stuff
I'll start.

<div class="math"> \exists \, a,b \, \mid \, a,b \in \mathbb{Z}^+ \wedge \, a \, = \, b</div>
<div class="math"> ab \, = \, b^2 </div>
<div class="math"> (a \, + \, b)(a \, - \, b) \, = \, a(a \, - \, b) </div>
Divide through by <div class="math"> (a \, - \, b) </div>
<div class="math"> (a \, + \, b) \, = a </div>
<div class="math"> 2a \, = \, a </div>
<div class="math"> 2 \, = \, 1 </div>

I see what you did there. Also goddamnit you trolls are shit nowadays.

Proof that odd^2 is odd: A number is odd iff it is equal to 1 mod 2. 1^2 = 1 mod 2.

Not trolling! Just a young mathematician trying to share some proofs, I can't see anything wrong with it.

Spurious proof.

fuck yeah. Though the low level highschool proof given in OP's pic isn't that long and hard either.
Long, and hard.

Sorry if this isn't a legit proof, I didn't realise. Just trying to contribute.

Despite most people on this board I'm not one of them!
I realise the problem with my original post now, and I'm an idiot for not spotting it before, but can we please move on and get some fucking legit proofs going?
