So, there is no specific number from which the list of real numbers starts or ends. It goes to infinity towards both sides of the number line. Symbol of Real Numbers. We use R to represent a set of Real Numbers and other types of numbers can be represented using the symbol discussed below, But we can also "build" a set by describing what is in it. Here is a simple example of set-builder notation: It says "the set of all x's, such that x is greater than 0". In other words any value greater than 0. Notes: The "x" is just a place-holder, it could be anything, such as { q | q > 0 } Some people use ": " instead of " | ", so they write ...A symbol for the set of rational numbers The rational numbers are included in the real numbers, while themselves including the integers, which in turn include the natural numbers..

The symbol that is used to denote real numbers is R. The symbol that is used to denote integers is Z. Every point on the number line shows a unique real number. I am just being confused with the use of word "all" and "any". Saying " x can be any real number"means x represents just a SINGLE real number which can be any real number(e.g. 10,12,5,4,etc).since we have not specified which real number x represents,this means Roughly speaking x represents all real numbers but one at a time.You can use any compact notation of your choice as long as you define it well. Suppose, for example, that I wish to use R R to denote the nonnegative reals, then since R+ R + is a fairly well-known notation for the positive reals, I can just say, Let. R =R+ ∪ {0}.
