#piegate: only math can absolve your greedy pie-slicing sins

Is this a fair (25%) slice of the pie?

It was a quiet holiday evening on Reddit when user “u/timmyboy87” dropped a post that would rock the online math community and foundations of pie fairness forever.

Under the unassuming title, “[Request] Help me settle a family debate! How unfair was the slice of pie? Was it more than 25% of the pie? #PieGate,” an innocent question became a community obsession.

And by community, I mean just me.

While timmyboy87 didn’t reveal the full backstory, we can only imagine what sparked this request. Maybe it was a heated Thanksgiving dinner. Maybe it was someone sneaking an oversized piece while others weren’t looking. Or maybe it was the sheer chaos of dividing dessert in a world without pie-cutting rules.

The facts were clear: a slice had been taken, a family was divided, and only math could restore balance.

The anatomy of #piegate

Picture this: the pie in question was a beautiful, golden-crusted marvel. But one slice, one rogue wedge, was cut with reckless abandon. It wasn’t a clean quarter, nor was it a dainty sliver. No — this slice was bold, jagged, unapologetically asymmetrical. It practically screamed, “Find the nearest protractor because we’re going to need science to figure this one out.”
