Infinity is truly an interesting mathematical concept -- but a concept it
remains. Unlike "zero", which was also added to math after the rest of the
numbers, infinity is still put in quotation marks, and when infinity is
involved, mathematicians call it by different names -- like "improper"
integrals. However, ECheung76 is right that much of mathematics depends on
it -- infinity and zero are really the bedrock of calculus, and zero is
very important in linear algebra.
