What are the counting numbers zero and their opposites?

Counting numbers, also known as natural numbers, typically refer to the positive integers starting from 1 (1, 2, 3, ...). Zero is not considered a counting number, but it is a whole number. The opposite of a counting number is its negative counterpart; for example, the opposite of 3 is -3. Thus, while counting numbers are positive, their opposites are negative integers.
