Question

true or false: when you are adding or substracting, the final answer should have the same total number of significant figures as whichever value has the fewest.

Explanation:

When adding or subtracting, the rule for significant figures is based on decimal places, not the total number of significant figures. The result should have the same number of decimal places as the value with the least number of decimal places, not the least number of total significant figures. So the statement is false.

Answer:

False
