1/0 = ∞

2/0 = ∞

clearly

∞ = ∞

therefore

1/0 = 2/0

multiply both sides by 0

1 = 2

For reference, this is terrible, pedantic and pointless Python.

Code:
```def oneisTwo():
one = 2
print("1 is equal to: {0}".format(one))
oneisTwo()```
Output:
Code:
`1 is equal to: 2`

WTF I am so mad rn

I post an original proof and she rips it off using algebra (and a similar mathematical fallacy) and she gets all the reps.

∞ is not a number, and division by zero is not defined,

If it's not a number then why does it have its own Wikipedia page?

I see where you went wrong:

It is all correct, but a2 - b2 would be equal to zero. 2(0) = 1(0)

Ur method is not proving. Algebra is more important in proving.

I'd like to see OP disprove this. The code quite literally shows that 1=2.

It is a concept, not a number. All numbers are concepts, but not all concepts are numbers, and infinity belongs to the latter. It is not a number. It is a concept related to numbers, but is itself not a number.

No. 1/0 is not infinity. 1/0 isn’t defined in our number systems: it’s not a number. In fact, it’s not just not a number, it’s not defined. It’s a meaningless expression. Asking what 1/0 is is like asking “What’s the square root of a slice of cheese?”. (CheeseIsVeg)

Isn't it impossible to prove because you'll always have to divide by zero at some point?

This code starts with the axiom that one is equal to two. This is a bit like proving that the Earth is round because it is round.

Some proofs don't involve division by zero, but they're still wrong. I saw a (incorrect) proof involving the imaginary number i (square root of -1)
