Large-number notation describes how to write very large numbers compactly. Standard form writes a number as a decimal times a power of ten, like 1.23 × 10^6. Scientific notation is similar but with a coefficient between 1 and 10 under ten's exponent. These systems help scientists, engineers, and students work with huge quantities without excessive digits.
