Is the sum of natural numbers a natural number?

The set of natural numbers, {1,2,3,4,5,…}, is sometimes written N for short. The whole numbers are the natural numbers together with 0. The sum of any two natural numbers is also a natural number (for example, 4+2000=2004), and the product of any two natural numbers is a natural number (4×2000=8000).

How do you proof a number is a natural number?

Proof by (Weak) Induction When we count with natural or counting numbers (frequently denoted {displaystyle mathbb {N} }), we begin with one, then keep adding one unit at a time to get the next natural number. We then add one to that result to get the next natural number, and continue in this manner.

What is the definition of factors in math?

Factors Definition: The factors of a number are defined as the number which can be multiplied to get the original number. By multiplying two factors of a number, a product is obtained which is equal to the original number. It should be noted that factors of any number can be either positive or negative.
