Convert numbers to and from scientific notation, and perform arithmetic operations in scientific notation.
Enter values as: mantissa × 10^exponent

| 10⁻⁹ | 0.000000001 | Nano | n |

Scientific notation expresses numbers as M × 10^n, where 1 ≤ |M| < 10 (the mantissa) and n is an integer (the exponent). It makes very large or very small numbers easier to work with.
Multiply: multiply mantissas, add exponents. (3×10⁴) × (2×10³) = 6×10⁷
Divide: divide mantissas, subtract exponents. (6×10⁷) ÷ (2×10³) = 3×10⁴
Add/Subtract: first make exponents equal, then add/subtract mantissas.
