1 이상 10 미만의 계수에 10의 거듭제곱을 곱하여 수를 표현하는 방법(예: 6.022 × 10²³).
설명
Scientific notation keeps calculations tractable across extreme scales. The mass of an electron is 9.109 × 10⁻³¹ kg; the mass of the Sun is 1.989 × 10³⁰ kg — both unwieldy in standard form. Multiplying them requires only adding exponents: 10⁻³¹ × 10³⁰ = 10⁻¹.
