Summation is denoted by the Greek letter Sigma notationΣ. Summation notation formula The equation to find the sum of the series is given below. Where, iis the starting value, and nis the upper limit. Types of summation There are two types of summation. ...
Some formulas require the addition of many variables; summation notation is a shorthand way to write a concise expression for a sum of a variable’s values. The formula contains the uppercase Greek letter sigma (Σ), which is why summation notation is sometimes called sigma notation. The “...
In the Appendix to Arithmetic, we saw that the sum of consecutive numbers -- a triangular number -- is given by this formula:½n(n + 1),where n is the last number in the sum. That is,Example 4. Cite the theorems of summation to prove:...

The notation implies that Drr, Apa and Grr are 3-dimensional arrays, and C and Csf are 1-dimensional arrays. The sigma formula says that we sum Drr*Apa*(C-Cnf) + Grr*Apa*(C-Csf)for eachi, j and k -- that is,for each cellidentifiedby eachi,j,k in Drr, Apa and Grr andby ...
