The Expanded Form Of Natural Numbers

When we write the expanded form of a natural number then it can be written in exponential form.

Example

247983 = 2 \times 100000 + 4 \times 10000 + 7 \times 1000 + 9 \times 100 + 8 \times 10 + 3 \times 1

= 2 \times 10^{5} + 4 \times 10^{4} + 7 \times 10^{3} + 9 \times 10^{2} + 8 \times 10^{1} + 3 \times 1

Some Important Points to Remember

  • (-1)odd number = (-1)
  • (-1)even number = (1)
  • a3b2 ≠ a2b3
  • a2b3 = b3a2
