Introduction to Positive Integers

What Are Positive Integers?

Positive integers are the set of numbers you count with: 1, 2, 3, 4, and so on. These numbers have no fractions or decimals, and they are always greater than zero.

Why Are They Important?

Positive integers are the building blocks of mathematics! You'll see them everywhere, from counting apples in a basket to keeping score in sports.

Key Properties

  • Always greater than zero
  • No fractions or decimals
  • Whole numbers only

Fun Facts

  • Zero is not a positive integer.
  • Every positive integer has a unique position on the number line.

Applications

You use positive integers whenever you count objects, measure steps, or keep track of time.

Examples

  • Counting 7 marbles in a jar.

  • Measuring 15 minutes on a clock.

In a Nutshell

Positive integers are the whole numbers greater than zero used for counting and ordering.

Key Terms

Integer
A whole number that can be positive, negative, or zero.
Natural Number
A positive integer used for counting (1, 2, 3, ...).
