cardinal (1, 2, 3, ...) and ordinal (1st, 2nd, 3rd, ...)
or rational and irrational
A rational number can be expressed as a fraction
ex: 22/7 is roughly 3.14, very close to pi, but not pi which is still real but...
Irrational - it cannot be expressed in the form of a fraction, other Irrational Numbers: sqrt(2), e.
No, all real numbers are classified as either rational or irrational. Rational numbers can be expressed as the quotient of two integers, while irrational numbers cannot be expressed as such and have non-repeating, non-terminating decimal expansions. Thus, there are no real numbers that fall outside these two categories.
Negative rational numbers; Negative real numbers; Rational numbers; Real numbers. The number also belongs to the set of complex numbers, quaternions and supersets.
Yes, square of 2 is a real number. Real numbers fall into 2 categories, Rational and Irrational. Square of 2 is an irrational number.
There are two real numbers and infinitely many complex numbers.
The two main DISJOINT subsets of the Real numbers are the rational numbers and the irrational numbers.

Odd and even.
rational numbers and irrational numbers
Between two different real numbers, there is an infinite amount of other real numbers. You can easily get one of them by taking the midpoint - i.e., calculate the average of the two numbers (add them, and divide the result by 2).
The two main divisions are rational numbers and irrational numbers.
Yes. There are infinitely many rational numbers between any two real 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 ...
Yes, square of 2 is a real number. Real numbers fall into 2 categories, Rational and Irrational. Square of 2 is an irrational number.
Whenever you multiply two negative real numbers.
There are two real numbers and infinitely many complex numbers.
The two main DISJOINT subsets of the Real numbers are the rational numbers and the irrational numbers.
2 and 3.
