∞ + ∞ = ?

∞ - ∞ = ?

∞ / ∞ = ?

∞ x ∞ = ?

∞ / (∞ / 2) = ?

1 / ∞ = ?

All of those are invalid since infinity isn't a number, it's a concept.

Asking what 1 / ∞ is is like asking what 1 / 0 is. It's undefined.

Indeed. Using set notation:

R = Set of real numbers.
Z = Set of integers (-2, -1, 0, 1, 2, ...)

|x| = Number of values in set x.

We get:

|R| = ∞
|Z| = ∞

Yet |R| > |Z| (it's bigger by a factor of ∞ precisely)

∞ + ∞ = infinity

∞ - ∞ = indeterminate (can indeterminate forms be applied to non-limits?)

∞ / ∞ = indeterminate

∞ x ∞ = infinity

∞ / (∞ / 2) = indeterminate

1 / ∞ = 0

You can't add or subtract from infinity because its not a real number.

What basis do you have for giving him a cigar when 3 of his answers are wrong?
