The real number system is a mathematical field. To start with, the Real number system is a Group. This means that it is a set of elements (numbers) with a binary operation (addition) that combines any two elements in the set to form a third element which is also in the set. The Group satisfies four axioms: closure, associativity, identity and invertibility. In addition, it is a Ring. A ring is an Abelian group (that is, addition is commutative) and it has a second binary operation (multiplication) that is defined on its elements. This second operation is distributive over the first. And finally, a Field is a Ring over which division - by non-zero numbers - is defined. The algebraic structures (Group, Ring, Field) are more than a term's worth of studying. There are also several mathematical terms above which have been left undefined to keep the answer to a manageable size. You can find out more about them using Wikipedia but be sure to select the hit that has "mathematical" in it!
The five axioms, or postulates proposed by Peano are for the set of natural numbers: not real numbers. They are:Zero is a natural number.Every natural number has a successor in the natural numbers.Zero is not the successor of any natural number.If the successor of two natural numbers is the same, then the two original numbers are the same.If a set contains zero and the successor of every number is in the set, then the set contains the natural numbers.
Because the first whole number, as defined by Peano's axioms for number is zero.
No, they are not the same. Axioms cannot be proved, most properties can.
They are called axioms, not surprisingly!
Axioms cannot be proved.
I don't know why there should be 4 laws (=axioms) specifically. In mathematics you can choose whatever system of axioms and laws and work your way with those. Even "logic" (propositional calculus) can be redefined in meaningful ways. the most commonly used system is Zermolo-Fraenkel+choice: http://en.wikipedia.org/wiki/Zermelo%E2%80%93Fraenkel_set_theory#Axioms It has 9 axioms though, not 4. One might want to take into consideration the rules of "logic" as basic laws: http://en.wikipedia.org/wiki/Propositional_calculus Another common set of axioms that can be created inside the ZFC system is peano arithmetic: http://en.wikipedia.org/wiki/Peano_arithmetic I hope I understood your question. The short answer is "there is no such thing". I think the questioner may have meant the 5 fundmental laws in mathematics, also known as the axioms of arithmetic, these are as follows: A1 - for any such real numbers a and b, a+b=b+a, the commutative law A2 - for any such real numbers a,b and c, a+(b+c) = (a+b)+c, the associative law A3 - for any real number a there exists an identity, 0, such that, a+0 = a, the identity law A4 - for any real number a there exists a number -a such that a+(-a)=0, the inverse law A5 - for any real numbers a and b, there exists a real number c, such that a+b=c, the closure property. These 5 axioms, when combined with the axioms of multiplication and a bit of logic/analytical thinking, can build up every number field, and from there extend into differentiation, complex functions, statistics, finance, mechanics and virtually every area of mathematics.

Peano axioms was created in 1889.
Axioms - album - was created in 1999.

There is no whole number without a predecessor. According to Peano's axioms, the number natural 0 has no predecessor.
There is no LAST natural number. According to Peano's axioms for numbers, every natural number has a successor.
According to Peano's axioms' it is the name given to the successor of the successor of the successor of 0.
In Peano's axioms, the successor to any integer n is n+1.
