### Significant Figures Rules

Significant figures represent the precision of a measurement.

**Rules for Counting:**
1. All non-zero digits are significant
2. Zeros between non-zero digits are significant
3. Leading zeros are NOT significant
4. Trailing zeros in decimal numbers ARE significant
5. Trailing zeros in whole numbers may or may not be significant

**Examples:**
- 5.230 has 4 significant figures
- 0.0052 has 2 significant figures
- 1,000 has 1-4 significant figures (context-dependent)

Practical Examples

Worked Calculation Example: Multiplication (12.40 × 2.1)

1. Determine sig figs of inputs:
   12.40 -> 4 significant figures
   2.1   -> 2 significant figures

2. Multiply exact numbers:
   12.40 × 2.1 = 26.04

3. Round to lowest input sig figs (2 sig figs):
   Result = 26

Common Significant Figures Calculator Mistakes to Avoid

Miscounting Trailing Zeros Without Decimal Points: Counting trailing zeros in integers without decimals as significant (e.g., $500$ has 1 sig fig; $500.$ has 3 sig figs).
Counting Leading Zeros as Significant: Counting leading zeros in decimals as significant (e.g., $0.0025$ has 2 sig figs, not 5).
Confusing Addition Rule with Multiplication Rule: Applying multiplication rules (least total sig figs) to addition/subtraction (which rounds to least decimal places).
Rounding Intermediate Calculations Early: Rounding steps prematurely during multi-step operations instead of rounding only the final result.
Treating Exact Defined Numbers as Having Limited Sig Figs: Applying sig fig limits to exact defined constants (e.g., $1\text{ inch} = 2.54\text{ cm}$ has infinite precision).
Dropping Trailing Zeros After Decimal Points: Omitting trailing zeros after decimals when converting to scientific notation (e.g., writing $3.4 \times 10^{-2}$ instead of $3.40 \times 10^{-2}$ for 3 sig figs).
