The sum of the first 57 natural numbers is 1,625.
Assuming the first five numbers is meant to refer, not to the first five real numbers but to the first five positive integers, the answer is 1*2*3*4*5 = 120
The natural numbers are positive integers (whole numbers) starting from one. So, the first natural number is 1, the second natural number is 2, the third is 3, and so on.
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.
