**The first 10 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10.** A natural number refers to any integer that is equal to or greater than 1, although 0 is included in some mathematical fields.

Natural numbers are primarily used in counting. When counting the number of objects, negative numbers and fractions are typically not needed. Many mathematical relationships and concepts can be related or determined from natural numbers. For example, when prime numbers are studied, natural numbers are almost exclusively examined. Natural numbers can also be used to order different values or objects, like ordering the competitors in a race from first to last.
