In mathematics, two equations with infinite symbols are occasionally used, namely: ∞ =∞+ 1, ∞ =∞× 1. A formula in which positive values represent infinity. There is no specific number, but positive infinity means a value greater than any number. The sign is +∞, and the sign of negative infinity is -∞.
Infinite or infinite, the mathematical symbol is ∞. It comes from the Latin "infinitas", which means "no boundary". It has different concepts in theology, philosophy, mathematics and daily life. Usually the use of this word does not involve its more professional definition.

In mathematics, infinity is related to the following topics or concepts: mathematical limit, Alev number, class in set theory, Dai Dejin-infinite group, Russell paradox, hyperreal number, projective geometry, extended real number axis and absolute infinity. In some themes or concepts, infinity is considered as a concept that is added beyond the boundary, rather than a number.
In pop culture, Buzz Lightyear's mantra in Toy Story is "To infinity and beyond!" This sentence can also be regarded as the cry of set theorists who study large cardinality. Since the power set of an infinite set always has a higher cardinality than itself, it can be proved that the number of infinite cardinality is infinite by constructing a series of power sets.
However, interestingly, the number of infinite cardinal numbers is more than any cardinal number, so it is an "infinity" bigger than any infinity, and it can't correspond to a cardinal number, otherwise it will produce a form of Cantor's paradox. The mathematical number response of number change is now like redundant induction to decode relay number.
