Numerical Format & Precision Guide

• Scientific Notation: For large or small powers of 10, write in standard exponential notation: e.g. 2.335 × 10²² → 2.335e22 (or 1.5 × 10⁻⁴ → 1.5e-4).

• Significant Figures & Tolerance: Standard significant figures and rounding are evaluated automatically within the ±1% error tolerance.

• Pure Numbers: Do not type unit strings (e.g. km/s) into the input box — units are fixed per question.
