I'm not convinced that there's a rule that's not either hell or meta

This post passes rule 3

This post passes no rules

∑_n=0^∞(⌈∫₀⁴ x/(x²+x+2) dx⌉)^π n²/2^n-1 = ∑_n=0^∞(1)^π n²/2^n-1 = ∑_n=0^∞ n²/2^n-1 = ∑_n=0^∞ ((n+1)C2+((n)C2))/2^n-1 = (3/2)*∑_n=0^∞ ((n+1)C2)/2^n-1 = (3/2)*(∑_n=0^∞ 1/2ⁿ)³ = 3/2*(2)³=3/2*8=12
