The specific example actually was a sum of 3 terms, Perhaps, I should have used an example calculation that followed the same pattern as in the introduction to that problem. Sorry for the confusion. However, the point that you want to remember is that for either adding or subtracting (or a combination of adding and subtracting) the variance in the result is the sum of the variances in each term.
You sir just helped me and I want to thank you
i have a question, isn't it supposed to be x+y-z ? then how did the value summed up in the next calculation
