    I'm a bit confused by the formatting but I think this is what you want:

    natural numbers: [1, infinity], no commas

    whole numbers: [0, infinity], no commas

    integers: [-infinity,+infinity], no commas

    rational numbers: every real number which can be written as a/b - > [-infinity,+infinity], with commas

    irrational numbers: every real number which can't be written as a/b - > ones with infinite non repeating comma digits

    0: whole number (-> also integer and rational)

    -10^2=100=natural number (-> also whole number, integer and rational)

    1.35=135/100=rational number

    -90=integer (->also rational)

    2/0=undefined ... so not any kind of number

    30^2=natural number (-> also whole number, integer and rational)

    -1=integer (-> also rational number)

    5.222 ... = 5+2/9=47/9=rational number (don't get confused by repeating sequences of numbers, they are not irrational)
