In mathematics, two equations with infinite symbols are occasionally used, namely: ∞=∞+ 1, ∞=∞× 1. Addition, subtraction, multiplication, division, multiplication and square root of +∞ and positive real numbers always result in +∞; -∞ and positive real numbers are added, subtracted, multiplied, divided, multiplied and squared, and the result is always-∞. (0 ×∞ is meaningless).

In the process of change, the absolute value of a variable is always greater than an arbitrarily large positive number. This variable is called infinity and is represented by the symbol ∞. For example, when the value of n is 1, 2, 3, 4…, 2n is infinite.

Unlimited application:

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 theology, for example, in the works of theologian Dunce Scott, the infinite energy of God is applied to the unconstrained, not the infinite. In philosophy, infinity can be attributed to space and time. In theology and philosophy, infinity is infinity, and many articles have discussed infinity, absoluteness, God and Zeno paradox.

In mathematics, infinity is related to the following topics or concepts: mathematical limit, Alev number, class in set theory, Dai Dejin's infinite group, Russell paradox, hyperreal number, projective geometry, extended real number axis and absolute infinity.
