Let's just say that 1 is a prime number, for fun.

Solve these, you know...for fun. :)

<div class="math">\frac{x+1}{x+2} = \frac{x+3}{x+5}</div>
<div class="math">\frac{x+3}{x+5} = \frac{x+7}{x+11}</div>

Let's just rewrite most of classical number theory, for fun.

Yeah, thanks, I already know x = 1 for both.

It was for fun.

I thought it would work for all primes, but it don't. :(
