Eli5: How does pie have so many digits? Why was it created? What other use does it serve?

Question

Like, it’s just a number why is it SO specific? Other than circles I can’t think of a use that pie has. Why would we create something that only has one use (that I know of) that is almost always simplified?

Answer 1

I mean, if a pie is really good then of course everyone wants a digit or two in there. Especially if it’s blueberry. This is where the expression “to have a finger in the pie” comes from.
