What is Scientific Notation?

Scientific notation (also called standard form or exponential notation) is a way of writing numbers that are too big or too small to be conveniently written in decimal form. It's commonly used in mathematics, engineering, and science to represent very large or very small numbers concisely.

Example:

The number 6,500,000,000 can be written in scientific notation as 6.5 × 109 or 6.5e9.

The number 0.000000042 can be written as 4.2 × 10-8 or 4.2e-8.
