Natural number
(1,2,3,4,........,n)
1 is the smallest natural number

Whole number
(0,1,2,3,.......,n)

Integers
(-n,......,-3,-2,-1,0,+1,+2,+3,........,+n)

Rational numbers
All numbers of (p/q) form where (q≠0)...
Eg. 1/4= 0.25 #terminating decimal
1/3= 0.3333 # non terminating decimal

There are some exceptions: π,√2,√3 etc. Are not rational number

Irrational Numbers
Numbers can not written in the form a/b with a&b as an integers...
Irrational Numbers are not #terminating & #not_repeating.

Eg. π, √5 & numbers in the form 0.26383518.... etc Are irrational Numbers

Prime Numbers
Numbers Divisible by 1& Itself are nothing but the #prime numbers.

Composite Numbers
Numbers other than prime & divisible by 1, Number itself & #by_other numbers also

The numbers 0 and 1 are neither prime nor composite. They are too special because they represent nothingness (zero) and wholeness (one), so the idea of having factors for 0 and 1 does not make sense....

Real Numbers
Numbers On line... Its set of numbers contains...
#Natural Numbers
#Whole Numbers
#Prime Numbers
#Composite Numbers
#Rational_&_Irrational Numbers... also🤘

Encircled are #Prime_numbers Other are #Composites Except '1'...

Compex Numbers
Numbers expressed in the form a + bi where a & b are real Numbers & #_i is imaginary number (i.e. i=√(-1) )...

Even Numbers
Numbers Divisible by 2...
Eg. 4, 6, 8, 10,......

Odd Numbers
Numbers not Divisible by 2
Eg. 1, 3, 5, 7,...
