How scientific notation works
Scientific notation expresses numbers as a coefficient (between 1 and 10) multiplied by a power of 10. For example, 4500 = 4.5 × 10³ and 0.0032 = 3.2 × 10⁻³. To multiply, multiply the coefficients and add the exponents. To divide, divide the coefficients and subtract the exponents. Then normalize so the coefficient is between 1 and 10.
