Frequently asked questions
What is scientific notation good for?
Writing numbers like 0.00042 (4.2 x 10^-4) or 9,300,000 (9.3 x 10^6) compactly and comparing magnitudes at a glance.
What is E notation?
A computer-friendly form: 4.2e-4 means 4.2 x 10^-4. Calculators and code use it widely.
How do I read the exponent?
A positive exponent means a large number; negative means a small fraction. Its size is how many places the decimal shifts.
