Spot the Mathematical Fallacy

[The_Flying_Skeptic]

b + b = b

There is only one way for that to be true and that's if b is 0

[Darwinian]

Or b is infinity.

[Tiberius]

No, because infinity + infinity is undefined

[fr0d0]

Oh dear

No, because infinity + infinity is undefined

Sorry not b quite true. you can say for b=Infinity (wish I could rotate 8 by 90 degrees) that b + b = b assuming you are using the same Aleph Infinity. Check out the Hilbert Hotel.
Actually in Mathematics 0 and Infinity are closely linked.

All the best

Hilbert's Hotel covers an entirely different concept...the countability of infinities in set theory. It has nothing to do with addition, which is what we were talking about here.

You can't add infinity to infinity since infinity is not a value but a concept. It would be like adding "the taste of jam" to "the taste of milk" and saying it equates something mathematical.

There are countably infinite sets, and non-countably infinite sets, but that doesn't mean that infinity is anything more than a concept.

The answer, by the way, is 42
