There are infinitely many subsets of Real numbers. In fact, there are infinitely many subsets of all the Reals in the interval [0,1].
For example, pick any number, x such that 0<x<1.
Then the subset [0,x] is a subset and x can be chosen in infinitely many ways.
The real number system can be sliced and diced in an infinite number of ways. In other words, you can't list all the different sets of numbers in the real number system. However, here are some of the commonest:the real number system itself (on the grounds that every set is a subset of itself)the integersthe whole numbers: 1, 2, 3, ...the even number: ..., -6, -4, -2, 0, 2, 4, 6, ...the rational numbers
It kind of depends on what "these" sets are.
Oh, dude, -6 belongs to a few different sets of numbers. It's a whole number, an integer, a rational number, and a real number. So, like, it's basically part of the big happy family of numbers.
set of real number....
It is an irrational number, and therefore a real number.
There are infinitely many sets of this type. Some of the common sets include natural numbers, integers, rational numbers, real numbers, complex numbers. Also, as an example, all sets of multiples of some whole number, for instance: { ... -6, -4, -2, 0, 2, 4, 6, ...} {... -9, -6, -3, 0, 3, 6, 9, ...} etc.
The set of Real NumbersThe set of Imaginary Numbers
Real number set, imaginary number set, and their subsets.
Yes, seven is a real number.
Yes it will be. The set of real numbers can be divided into two distinct sets: rational and irrational. So if it is not rational, then it is irrational.
It can be element of: Rational numbers or Real numbers
It is an integer, a rational, a real, a complex number. It is the additive identity for all of the above sets.
