When you add two numbers together the result is called the sum.1 + 2 = 33 is the sum of 1 and 2.
The numbers 1, 2, 3, 4, 5.... are called the natural numbers, or sometimes, the counting numbers.
Any whole number such as 1, 2, 3, 4 and so on.
Numbers having only 2 factors are prime numbers. Their only factors are 1 and themselves. Prime numbers. The only two factors should be 1 and itself.
0, 1, 2, 3, 4, etc. are called Cardinal Numbers.
Numbers such as 0, 1, 2, 3 are also called the wholenumbers.*apex* ---->>Counting-PurpleLicious-

The set of numbers {1, 2, 3, 4, …} is called the Natural Numbers. These numbers could also be called the counting numbers or the cardinal numbers.
In any addition problem, such as 1 + 2 = 3, the numbers 1 and 2 are called addends. The total is called the sum.

The numbers 1, 2, 3, 4, 5.... are called the natural numbers, or sometimes, the counting numbers.
Natural numbers are non-negative whole numbers (no decimals or fractions). This would be 0, 1, 2, 3, 4, 5, 6, etc...
9 (factors 1, 3, and 9) and 10 (factors 1, 2, 5, and 10) are coprime numbers. Numbers are coprime (also called relatively prime) if 1 is their only common factor.

"Natural Numbers" can mean either "Counting Numbers" {1, 2, 3, ...}, or "Whole Numbers" {0, 1, 2, 3, ...}, depending on the subject.
