natural numbers
One, two, three…
Natural numbers are the counting numbers: 1, 2, 3, 4, and so on indefinitely.
Mathematicians disagree about whether zero belongs in the set—some include it, others don't.
Natural numbers are positive, whole, and the most intuitive numbers humans work with: The natural numbers are infinite.
