# Multiply

This function block multiplies a set of numeric inputs and outputs the resulting product. It is useful for scaling values, combining factors, and simple math chains in your visual flow.

## 📥 Inputs <a href="#inputs" id="inputs"></a>

`Number` Socket(s) — one or more numeric input sockets (default: 2).\
This block accepts multiple numeric inputs; the active inputs are multiplied together.

## 📤 Outputs <a href="#outputs" id="outputs"></a>

`Number` The product of all connected numeric inputs.

## 🕹️ Controls <a href="#controls" id="controls"></a>

`Input size` A dropdown to set how many numeric input sockets the block provides (adjustable number of inputs from the UI).

## 🎯 Key Features <a href="#features" id="features"></a>

* Dynamic input count — expand or shrink the available input sockets to match how many values you want to multiply.
* Simple numeric operation — multiplies all connected inputs and returns a single numeric result.
* Works well inside math or data-processing chains where a single combined numeric value is required.

## ⚙️ How it runs <a href="#running-mechanism" id="running-mechanism"></a>

* The block reads all currently connected numeric inputs.
* Unconnected inputs are ignored.
* It computes the product of the provided numbers and outputs the final numeric result.
* Use the `Input size` control to change how many inputs are available before running.

## 📝 Usage Instructions <a href="#usage" id="usage"></a>

1. Set the desired number of inputs with `Input size`.
2. Connect numeric sources (constants, measured values, counters, etc.) into the available `Number` sockets.
3. Read the result from the output `Number` socket and pass it to downstream blocks.

## 💡 Tips and Tricks <a href="#tips-and-tricks" id="tips-and-tricks"></a>

* Combine with `Number Input` or `Number Range` to provide configurable constants or parameters to multiply with measured values.
* Use with `Add`, `Subtract`, or `Divide` to build arithmetic pipelines (for example: compute a scaled offset by combining `Add` and `Multiply`).
* When working with lists or batches, pair with `Batch Processing`, `Get Element`, or `Debatch` to multiply elements in a sequence.
* Use `Round` or `Absolute` after this block to format or normalize the result for display or export.
* Feed the output into `Scope` or `CSV Export` to visualize or log computed numeric results over time.
* For counting-based calculations, combine with `Counter` or outputs such as `Object Count` from detection blocks to compute rates or totals.

## 🛠️ Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

* If the result is unexpected, check each connected `Number` input for correct values and ensure the intended sockets are connected.
* If you need to multiply a large number of values, increase `Input size` before connecting all sources.
