Infinity is not really a number. It is a symbol (<math>\infty</math>) for something that is so large that we cannot imagine it. You can also think of it as being the opposite of zero (0), where zero is nothing and infinity an unimaginable amount.
In multiplication you are looking at a certain number of sets of things. For example, you could have three sets of four things where each set as four things in that set. You can tell how many are present by using the mathematical equation 3 x 4 or twelve things.
If you were to have an infinity set of infinity things you would still be left with an infinity amount of things. It is the same as saying if you have no sets of no things you have no things (0x0=0). So, the answer to the question is that infinity times infinity is infinity.
The use of infinity is not very useful in arithmetic, but is used in more advance levels of mathematics.
Infinity times infinity is not a well-defined mathematical operation. In mathematics, infinity is not a number but a concept representing something unbounded or limitless. Therefore, the result of multiplying infinity by infinity is undefined and cannot be determined within the realm of standard arithmetic.
There is no number greater than infinity. Infinity is defined to be greater than any number, so there can not be two numbers, both infinity, that are different.However, when dealing with limits, one can approach a non-infinite value for a function involving infinity. Take, for example, 2x divided by x, when x is infinity. That value is indeterminate, because infinity divided by infinity is defined as indeterminate, and 2 times infinity is still infinity.But, if you look at the limit of 2x divided by x, as x approaches infinity, you do get a value, and that value is 2. This does not mean that 2x when x is infinity is twice infinity, it just means that, right before x becomes infinity, the ratio is right before 2.Infinity should not be thought of as a number, but rather as a direction. Whereas a number represents a specific quantity, infinity does not define given quantity. (If you started counting really fast for billions of years, you would never get to infinity.) There are, however, different "sizes of infinity." Aleph-null, for example, is the infinity that describes the size of the natural numbers (0,1,2,3,4....) The infinity that describes the size of the real numbers is much larger than aleph-null, for between any two natural numbers, there are infinite real numbers.Anyway, to improve upon the answer above, it is not meaningful to say "when x is infinity," because, as explained above, no number can "be" infinity. A number can approach infinity, that is to say, get larger and larger and larger, but it will never get there. Because infinity is not a number, there is no point in asking what number is more than infinity.
infinity? Infinity over zero is undefined, or complex infinity depending on numbers you are including in your number system.
Positive: (0, infinity)Nonnegative: [0, infinity)Negative: (-infinity, 0)Nonpositive (-infinity, 0]
Impossible to answer ! Infinity is a never ending quantity - and Pi is a never ending decimal !
Yes, except that infinity is not a number.
infinity
negative infinity
An unknown number x times infinity would be infinity.
infinity!
Ironically, the answer is: infinity (Infinity is a concept not a number)
Zero times infinity is defined as "indeterminate".
It is still infinity.
infinity. anything times infinity is infinity (with the exception of indeterminant forms like infinity/infinity)
Interesting. Assuming "times" is a variable: You're question is what is 0/times + times * (0/+0*100) That would be 0 + times * (0/0) 0/0 = infinity(Anything over 0 = infinity) So then, you can figure out that it is times * infinity which is infinity.
that would be 2 times infinity.
2 infinity and beond
Well, darling, technically speaking, infinity isn't a number, it's a concept representing something endless. So, if you wanna get all technical, two times infinity is still infinity because no matter how many times you multiply infinity by a finite number, you're still left with infinity. Math can be a real buzzkill sometimes, huh?
