When writing measured values the amount of decimals written reflects the precision of the instrument. 4. Accurate how close it comes to the published or accepted value Data Processing Adding and Subtracting The answer must contain the number of DECIMALS of the number with the fewest “x” uncertainties must be ADDED and a total uncertainty must be stated Example: Perimeter Question Multiplying and Dividing When multiplying and dividng the answer must contain the same number of significant FIGURES as the one with the fewest. As well as for operation involving the multiplication and division of uncertainties. Example: Uncertainties Metric System Exponent Number Short Form Symbol 1 000 000 000 000 Terta T 1 000 000 000
