Multiplicity of a root of a polynomial[edit] Let F be a field and p(x) be a polynomial in one variable and coefficients in F. An element a â F is called a root of multiplicity k of p(x) if there is a polynomial s(x) such that s(a) â  0 and p(x) = (x â a)s(x).
All of the row and column filters in the Pivot Table are used in the calculation of Qty for each cell in the Pivot Table. [Qty All]=Calculate(Sum([Quantity]),All(Orders). The CALCULATE function can be used to override row and column filter values.ll of the row and column filters in the Pivot Table are used in the calculation of Qty for each cell in the Pivot Table.
