Final answer:
The rule for breaking down numbers in equations to get exact results is to be aware of significant figures when mathematically manipulating numbers.
Step-by-step explanation:
The rule for breaking down numbers in equations to get exact results is to be aware of significant figures when mathematically manipulating numbers.
When performing multiplication and division, the final answer should have the same number of significant figures as there are in the number with the fewest significant figures.
When performing addition and subtraction, the answer should be given the same number of decimal places as the term with the fewest decimal places.
