It is different kinds of numbers including a decimal number, a positive number, a rational number and a real number.
Complex numbers include real numbers, pure imaginary numbers, and the combination of those two.
The real numbers are divided into rational numbers and irrational numbers.
here are rational numbers--numbers that you can express as a fraction irrational numbers--numbers you cannot express as a fraction integers--whole numbers and their opposites(negatives) whole numbers--0, 1, 2, 3,... natural or counting numbers--1, 2, 3,....
There is only one set of Real numbers.
Real numbers, imaginary numbers and irrational numbers are three kinds of numbers. Others are rational numbers, algebraic numbers and primes numbers. There are many more.

The real numbers are divided into rational numbers and irrational numbers.
Because in real numbers they are not defined.

They are whole numbers,counting numbers,integers,rational numbers,real Numbers,composite numbers,square numbers,positive numbers,2-digit numbers.
The different names for Numbers are defined as Natural numbers, whole numbers , real numbers, decimal numbers, integers, rational numbers and irrational numbers.
The "two" kinds of energy are real and vector energy. Mot accounting for the two kinds of energy is the cause of current confusion in physics. Newton and Einstein missed the two kinds of energy real and vector. The gravitational energy is E= -mu/r + mcV. The first kind of energy Newton got the real or potential energy -mu/r. The unaccounted for energy is the "vector" energy mcV. The vector energy is the source of "dark energy" and myriad mysteries in cosmology. The Universe has two kinds of numbers, real numbers and vector numbers. This gives two kinds of energy, and two kinds of forces ,etc,etc,etc. Quaternions are the answer to the "two kinds" of energy, "reals and vectors" or quaternions!
