Answer 10

`Natural numbers:`
\(\color{black}{ \displaystyle 1,~~2,~~3,~~4,~~5,~~6~~... }\)

`Whole numbers:`
\(\color{black}{ \displaystyle 0,~~1,~~2,~~3,~~4,~~5,~~6~~... }\)
(same as natural numbers, BUT INCLUDES ZERO)

`Integers:`
\(\color{black}{ \displaystyle ...~-6,~~-5,~~-4,~~-3,~~-2,~~-1,~~0~~1,~~2,~~3,~~4,~~5,~~6~~... }\)
(positive and negative whole numbers)

`Rational numbers:`
Fractions, like \(\color{black}{ \displaystyle 1/5,~ }\) \(\color{black}{ \displaystyle -4/9,~~~~10/7 }\) and on

Also, \(\color{black}{ \displaystyle \sqrt{16} }\) since it is really a 4) and all roots, if and only if the number inside is a perfect square (perfect cube or whatever)

(But Rational numbers also includes all integers)

`Irrational number`
Roots like, \(\color{black}{ \displaystyle \sqrt{3},~~\sqrt[8]{8} }\)
Also Euler (and other) special constants such \(\color{black}{ \displaystyle \pi,~e,~\psi~ }\)
Also logarithms
\(\color{black}{ \displaystyle \ln(2) }\), \(\color{black}{ \displaystyle \log_9{7} }\) ...
