Understanding Scientific Notation

Scientific notation is written as a product of a number between 1 and 10 and a power of 10. The format is:

a × 10^b

On calculators and in programming, this is often represented as "e" notation (e.g., `1.23e+7` means 1.23 × 10⁷).

A positive exponent (e.g., 10⁷) means the decimal point was moved to the right, indicating a large number.
A negative exponent (e.g., 10⁻⁵) means the decimal point was moved to the left, indicating a small number.
