Scientific Notation Guide
Scientific notation is a way of expressing very large or very small numbers compactly. A number is written as a coefficient (1 to 10) multiplied by a power of 10. For example: the speed of light is 3 x 10^8 m/s, written as 3e+8 in E notation.
Engineering notation is similar but restricts the exponent to multiples of 3, aligning with SI prefixes (kilo=10^3, mega=10^6, giga=10^9, etc.).
