Why is usual addition (+) a binary operation on the set of natural numbers (\mathbb{N})?

Answer and explanation

Correct answer: Because the sum of two natural numbers is a natural number

Step 1: Take any two numbers from (\mathbb{N}). Step 2: Their sum remains in (\mathbb{N}). Step 3: Since closure holds, usual addition is a binary operation on (\mathbb{N}).
