A way of expressing very large or very small numbers as a product of a number and a power of 10.
Scientific notation expresses numbers as a × 10^n, where 1 ≤ a < 10 and n is an integer. Examples: 299,792,458 (speed of light in m/s) = 2.99792458 × 10⁸, 0.000000001 (1 nanometer in meters) = 1 × 10⁻⁹. Scientific calculators support scientific notation and trigonometric, logarithmic, and exponential functions. It is essential in physics, chemistry, engineering, and advanced mathematics.
