Frequently Asked Questions
What is scientific notation?
Scientific notation expresses numbers as a coefficient between 1 and 10 multiplied by a power of 10. For example, 3,000,000 becomes 3 × 10^6. It makes very large or very small numbers easier to work with.
How do I multiply numbers in scientific notation?
Multiply the coefficients and add the exponents. For example, (2 × 10^3) × (3 × 10^4) = 6 × 10^7.
What is the difference between scientific and engineering notation?
Engineering notation restricts the exponent to multiples of 3 (matching metric prefixes like kilo, mega, giga), while scientific notation uses any integer exponent.
