Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ...

where the notation ... means the list goes on forever.

Positive Integers are numbers that can be written without a fractional or decimal component.

You might want to think of the positive integers as the numbers you could count with your fingers if you use at least one finger and you can keep using as many fingers as you want over and over again.

The set of positive integers is the same as the set of natural numbers.

To help you understand what are and what are not positive integers, here are some examples.

  • 100001 is a positive integer.
  • The square root of 2 is not since it is not a whole number.
  • 0.01 is not since it is not a whole number.
  • -2 is not since it is not greater than zero.
  • zero (0) is not a positive integer since zero is not a positive number.

It is any counting number. You start counting at 1, and then count to 2, and so on. The numbers you use to count with are positive integers. It is any real number greater than zero which has no digits to the right of the decimal point.
It is an integer or a counting number that is greater than zero. Examples are 1, 5, 170864, 329678, 99999999, and 5896725358
A positive integer is a whole number from zero onwards with no fractions or decimals right of the number line.
Counting numbers greater than zero.
A positive integer, in mathematics, is one of the natural, counting numbers, 1, 2, 3, 4, etc.

The answer to that one must forever remain a mystery, since we can't find

a definition anywhere that tells what an "interger" is.

There is a math word that looks a lot like it, though. The word is integer .

Positive integers are the whole numbers that are bigger than zero.
