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.
Since SUMIF() can be applied only to single row or column, your evaluation must be carried out in 2 steps. First use SUMIF() on rows and also concatenate the condition values for each summation in an adjacent cell. This concatenated string will serve as a key in next step. Next apply SUMIF() to the column that contains row sums, using the key from previous step as the condition. share|improve this answer.
