I feel like this is not so much a meme as just a thing that is wrong.

it's a reference to some calculators wrongly approximating some values to a fraction of π
Sadly, this is so far over my head that I have to accept it as truth, spread the word with authority, and found a religion based on it
This "proof" is based on a bug in Casio calculators (tested it on the fx-991EX classwitz, got it there too)
A try to explain it is in this video by Matt Parker. Are exactly the same numbers
It's not a bug, it's a feature
It's just an equation that gives you the first few digits of pi if you treat pi as a variable.
But, pi isn't a variable, so it's not a real equation.
it's not treating pi as a variable, though...
here's one that does work:
circumference = 2piradius,
so, pi = 2*radius/circumference... which is true... (pi is the ratio of diameter to circumference)
the meme here is just an equation that's wrong because it's wrong... pi is being treated as if it's some value that it's not in the first equation, and it's still wrong in the second equation...
pi is being treated as if it's some value that it's not in the first equation
That's a variable. The value of 'pi' is dependent on the rest of the equation.
If you treat it as a variable, the math gives you 3.1415926536.
Ahhh, gotcha! Thanks for the info :)
As a programmer, I know what a variable is. Therefore, now this all makes sense to me.
Maybe I am also too dumb, but isn't the issue that the first equation is just wrong? It assumes that pi only equals 3.141592654
Pi = pi/1
So P=p i imagine
