Studdy Solution
STEP 1
Assumptions1. We are performing addition and subtraction operations on the given numbers. . The rule for significant figures (SFs) in addition or subtraction is that the result should have the same number of decimal places as the number in the calculation with the least decimal places.
STEP 2
First, perform the addition and subtraction operations without considering the significant figures.
STEP 3
Now, look at the number of decimal places in each of the numbers in the original problem. The number with the least decimal places is23.65, which has two decimal places.
STEP 4
Therefore, the final answer should also have two decimal places. Round the result from Step2 to two decimal places.
The correct answer to the math problem is18.58.
