Who discovered the infinity?

What infinity symbol means?
The infinity symbol, a figure eight on its side, variously signifies the concept of limitlessness or eternity, especially as used notationally in mathematics and metaphorically with respect to love.
What’s the middle of infinity?
zero
Does positive infinity include 0?
It is a number, on the line of all real numbers from negative infinity to positive infinity 0 is included in that. The only numbers not within all real numbers are imaginary numbers (like sqrt(-x)).
Is negative infinity the same as infinity?
No. In number sets in which positive and negative infinity are both defined, they are not equal. There are sets, such as the extended complex numbers, in which there is only one kind of infinity, but they attach no meaning to infinity being positive or negative.
Does Infinity minus infinity equal zero?
It is impossible for infinity subtracted from infinity to be equal to one and zero. Using this type of math, we can get infinity minus infinity to equal any real number. Therefore, infinity subtracted from infinity is undefined.
What is the word infinity mean?
1a : the quality of being infinite. b : unlimited extent of time, space, or quantity : boundlessness. 2 : an indefinitely great number or amount an infinity of stars. 3a : the limit of the value of a function or variable when it tends to become numerically larger than any preassigned finite number.
Does Infinity have a middle?
Every point on an infinite line is its middle point. Because the line is infinite in length, any point will have infinite right side and infinite left side. Hence every point is a middle point for all practical calculations.
Does R include Infinity?
3 Answers. ∞ or −∞ are not elements of R. However, we have the extended real number system R∪{−∞,∞} (see here for more details) which contains ∞ and −∞ as its elements.
What is negative infinity minus negative infinity?
Infinity isn’t a number; it’s an endless series. One example would be the series of all whole numbers, which continues endlessly. The series of all odd numbers is also infinite. So infinity minus infinity is still infinity (at least, if you pick these particular infinite series).
