# Sum  Stream

> **Note:** **What is it about?**
>
> This page describes the **Sum Stream node** of the Scene Nodes system in **Cinema 4D**. 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.
