infinity

The value of infinity - 1 is still infinity. Adding or subtracting any finite number does not change the value infinity at all, because finite numbers are too small compared to infinity.

No, infinity is not a number, in the mathematical sense. It is a symbol for "unlimited". As such it has uses in various theories in math and in physics. The simplest proof is adding a real value, such as 1, to infinity. Just as zero times any number is still zero, infinity plus any value will remain "infinity".

Firstly we don't know infinity value. If you divide any number by infinity then answer will be zero. Example is divide 100/3 by infinity ( let infinity is equal to 1/0). Then answer is 100/3/1/0 you will get zero.

infinity

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.

the value of log0 is -infinity which is minus of infinity

Infinity is not a number and so there is no whole number after infinity.

No, because your number will always keep its value. Infinity is comprised of an infinite amount of numbers and your number is included in that set. It will have a lower value than all the numbers that come after it in a progressive manner but it will always keep its value.

Infinity is not a number in the ordinary sense of the word.

infinity

Infinity is sometimes considered as the largest number, BUT it is not the same sort of number as your familiar 1 to 9 and so on. Infinity is a concept, and as such it is of great value in mathematics. BUT it should never be used with regard to real items, such as the number of atoms or similar measure of magnitude.
