Answer:
Natural Number :-
Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity and are also used for counting purpose. It does not include zero (0). In fact, 1,2,3,4,5,6,7,8,9…., are also called counting numbers.
Whole Number :-
In mathematics, whole numbers are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on. ... Whole numbers include natural numbers that begin from 1 onwards. Whole numbers include positive integers along with 0.
Integers :-
Integer, whole-valued positive or negative number or 0. ... The integers are generated from the set of counting numbers 1, 2, 3,… and the operation of subtraction. When a counting number is subtracted from itself, the result is zero; for example, 4 − 4 = 0.
Rational number :-
In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

Ans 2
Associative property :- (a+b) + c = a+(b+c)
Distributive property :-
a(b+c) = ab+bc .
