About Scientific Notation

What is Scientific Notation?

Scientific notation is a way of expressing very large or very small numbers in a compact form. A number is written as the product of a coefficient (between 1 and 10) and a power of 10. For example, 300,000 is written as 3 × 10^5.

Notation Types

  • Scientific Notation: Mantissa × 10^exponent (e.g., 2.998 × 10^8)
  • Engineering Notation: Exponent is always a multiple of 3 (e.g., 299.8 × 10^6)
  • E-Notation: Computer format using 'e' (e.g., 2.998e8)
