How it works
Identify, count, and understand significant figures in physical measurements
Trailing zeros in a whole number without an explicit decimal are treated as scale placeholders. In real laboratory reporting, write with an explicit decimal (e.g. 1200. ) or in scientific notation ( 1.20 × 10³ ) to confirm precision.
All non-zero digits represent direct physical measurements taken with an instrument.
