I think that the monarchy would care as the UK obviously means a great deal to them but wonât cause too much concern so long as Scotland and Northern Ireland do not become republics. The UK and British monarchy are two very different institutions.
A series is a summation performed on a list of numbers. Each term is added to the next, resulting in a sum of all terms. Sigma notation is used to represent the summation of a series. In this form, the capital Greek letter sigma $\left ( \Sigma \right )$ is used.
Here, we have rearranged the order of summation, using the multiplicative properties of the exponential function. Note that the first sums in the numerator and denominator only involve, whereas the last sums omit the particular state from consideration (this is indicated by the superscript on the summation symbol).
