Origin of Symbol: Mobius belt is usually considered as the creative source of infinite symbol ∞, because if someone stands on the surface of a huge Mobius belt and walks along the "road" he can see, he will never stop. But this is an untrue rumor, because "∞" was invented before Mobius belt.

Arixtote (384-322 BC), an ancient Greek philosopher, believed that infinity could exist, because finite quantities were infinitely separable, but infinity could not be achieved.

/kloc-in the 20th century, a great Indian mathematician, Bascara, appeared, and his concept was close to that of theory.

The symbol of putting 8 horizontally as ∞ to represent infinity was first used in john wallis's paper Arithmetic Infinity (published in 1655).

This symbol is also the action made by Montbius Altman when he emits Montbium light. ?

Equation of infinite sign: ∞=∞+ 1, ∞=∞× 1.

Mathematical operations: 1/∞ and 2/∞ can only find the limit, and there is no exact value, because the denominator is uncertain. In the case of infinite denominator, the limit is 0, because there is no difference between 1 and 2.
