Halfway between infinity Watch
If zero is an infinite/undefined number, how can 1/2 or 0.5 be exactly halfway between zero and one?
*sorry if this question is offensive to mathematicians*

If you get 0 on a test, is your score undefined? Nope, you got 0.
0 is a real number.
In set theory: 0 is the cardinality of the empty set and the lowest ordinal number
(when empty set is wieved as well-ordered-set)
In abstract algebra: 0 is the zero element, which is the neutral element for addition
and absorbing element for multiplication (if defined in structure)
