Interval Notation
The real numbers between 1 and 6 form an interval on the number line. This interval is denoted as (1, 6), where the parentheses indicate that the endpoints 1 and 6 are not included. In interval notation, this set can be written as {x | 1 < x < 6}. This set includes all real numbers greater than 1 and less than 6.
A radian is simply a measurement unit. The relation between a radian and real numbers is similar to the relation between a degree and real numbers or a metre and real numbers.

There are uncountably infinitely many real numbers between 1080 and 1100. There are 21 integers between 1080 and 1100, including the "endpoints." They are: 1080, 1081, 1082, 1083, 1084, 1085, 1086, 1087, 1088, 1089, 1090, 1091, 1092, 1093, 1094, 1095, 1096, 1097, 1098, 1099, 1100.
Real numbers are infinitely dense. That means that between any two real numbers, there are infinitely may real numbers. One example: 2.00135
Integer numbers are a subset of real numbers. Real numbers may contain fractions.
Yes. There are infinitely many rational numbers between any two real numbers.
Rational numbers form a proper subset of real numbers. So all rational numbers are real numbers but all real numbers are not rational.

A real number is just an ordinary number. The set of real numbers include all numbers between negative and positive infinity. Real numbers are ordered, and thus do not include imaginary numbers. A subset of real numbers refers to a group, or subsection, of real numbers. For instance, the numbers between 5 and 22 are a subset of real numbers. Another example of a subset is all even numbers, or all odd numbers.
There are not just three real numbers but an infinity of them Not only that , between any two of them there is an infinity of real numbers. And between any two of them ...
Real numbers are a proper subset of complex numbers. In fact each complex number, z, can be represented as z = x +iy where x and y are real numbers and i is the imaginary square root of -1.Thus the set of complex numbers is the Cartesian product of two sets of real numbers. That is, C = R x R where C is the set of complex numbers and R is the set of real numbers. Limitations of this browser prevent me from writing that in a mathematically precise and more helpful fashion.
