Say Yes to New Learn New Concepts on Natural Numbers

Natural numbers include all the whole numbers excluding the number 0. In other words, all natural numbers are whole numbers, but all whole numbers are not natural numbers.

Natural Numbers = {1,2,3,4,5,6,7,8,9,…..}
Whole Numbers = {0,1,2,3,4,5,7,8,9,….}

  1. Natural numbers are the counting numbers, starting from 1 and going infinitely: 1, 2, 3, 4, 5, ...
  2. Natural numbers do not include zero or any negative numbers. They are always positive.
  3. Natural numbers are used to count objects, arrange items in a sequence, or indicate a position in an ordered list.
  4. Addition is an operation performed on natural numbers. Adding two or more natural numbers gives a sum.
  5. Subtraction is another operation performed on natural numbers. Subtracting a smaller natural number from a larger natural number gives a difference.
  6. Multiplication is the process of repeated addition. It is performed on natural numbers and gives a product.
  7. Division is the inverse operation of multiplication. It involves sharing or splitting a quantity into equal parts. Division of natural numbers gives a quotient.
  8. Natural numbers can be even or odd. An even number is divisible by 2 without leaving a remainder, while an odd number is not.
  9. Natural numbers can be prime or composite. A prime number has exactly two distinct factors: 1 and itself. A composite number has more than two distinct factors.
  10. Natural numbers have a unique property called the successor and predecessor. The successor of a natural number is obtained by adding 1, and the predecessor is obtained by subtracting 1.
