Unlike Arithmetic it accumulates a whole data stream — for example totaling all values delivered by a Range loop. Unlike the [Arithmetic Node](https://help.maxon.net/c4d/en-us/Content/html/NET_MAXON_NODE_ARRAY_ARITHMETIC.html.md), which can also be used to add values, the *Sum Stream Node* is designed to process a data stream. Any number of values can be passed to the Node, e.g., via a *Range* Node, and added there.
