Answer:
the answer is A. Added
Explanation:
Rule 1.
If you are adding or subtracting two uncertain numbers, then the numerical uncertainty of the sum or difference is the sum of the numerical uncertainties of the two numbers. For example, if A = 3.4± . 5 m and B = 6.3± . 2 m, then A+B = 9.7± .
more explanation:
What is the uncertainty of a value?
Uncertainty as used here means the range of possible values within which the true value of the measurement lies. This definition changes the usage of some other commonly used terms. For example, the term accuracy is often used to mean the difference between a measured result and the actual or true value.
hope it helps :)
