Significant figures (or digits) show the precision of a number. Hereโ€™s a quick guide to counting them:Non-Zero Digits: All non-zero digits (1-9) are always significant.Example: 123 has 3 significant figures.Leading Zeros: Zeros before the first non-zero digit are NOT significant.Example: 0.0056 has 2 significant figures (5 and 6).Trailing Zeros:If a number has a decimal point, trailing zeros after the last non-zero digit ARE significant.Example: 12.30 has 4 significant figures (1, 2, 3, 0).Without a decimal, trailing zeros are NOT significant unless specified (e.g., 1200 has 2 significant figures unless written as 1200. with 4).Zeros Between Non-Zero Digits: These are always significant.Example: 1008 has 4 significant figures (1, 0, 0, 8).Exact Numbers: Numbers from counting (e.g., 5 apples) or defined values (e.g., 100 cm = 1 m) have infinite significant figures and donโ€™t affect calculations.
