The table below will help the classification of numbers much. He went clear things. Of important observations, you need to do in the chart. Observation # 1:
Note that v (9) is a natural whole. It is because that v (9) = 3
Observation # 2:
Note that the only difference between the natural numbers and integers is zero.
= Integers numbers natural + zero
Comment # 3:
Note that the difference between integers and integers are negative numbers.
Integer = integer + the negative integers
Comment # 4:
Example:-2 is an integer and can be written as – 2/1 to make it a fraction.
However, – 1/3 =-0.333333333 is not an integer
Observation # 5:
Fractions can be written as a decimal of endpoint or a repeat decemal
Example: 1/2 = 0.5 and 0.5 are decimal endpoint. 1/3 = 0.3333333 and 0.3333333 are a recurring decimal
Comment # 6:
Comment # 7:
Example: pi = 3.14…, 2.224879566117426874, v (7)
Another way to see is that they are not repeating check digits or decimal endpoint
Comment # 8:
Comment # 9:
v(-7), v(1-8), v(-25) = 5i, etc….
