Frequently Asked Questions
What is scientific notation?
A number written as a × 10ⁿ where 1 ≤ |a| < 10 and n is an integer. So 0.00045 = 4.5 × 10⁻⁴ and 6,400,000 = 6.4 × 10⁶.
Why is scientific notation useful?
It makes very large or very small numbers readable and easier to multiply. Avogadro's number 6.022 × 10²³ is far easier than writing 24 digits.
How do I multiply numbers in scientific notation?
Multiply the coefficients and add the exponents: (3 × 10²) × (2 × 10⁵) = 6 × 10⁷. For division, subtract exponents.
What is the difference between scientific and engineering notation?
Engineering notation restricts the exponent to multiples of 3 (like SI prefixes kilo, mega). So 12,300 is 1.23 × 10⁴ scientific or 12.3 × 10³ engineering.
