"WebSummations are not like integrals. When you calculate an integral, swapping the boundaries does change the sign of the result. However, when talking about summations: ∑ n = − ∞ − 1 a ( n) = ∑ n = − 1 − ∞ a ( n) This holds because it is the same if we perform the sum of a ( − 1) + a ( − 2) +... + a ( − k) for any k > 0 in any order.
