# Math Multiply with Value

Multiply a key value with a new value and store the result in a new key.

## Example

This example shows how to use the MathMultiplyWithValue transformation to multiply the value of an existing key with a specified value and store the result in a new key.

```json
{
  "operation": "math_multiply_with_value",
  "arguments": {
    "key": "original_value",
    "value": 2.5,
    "new_key": "multiplied_value"
  }
}
```

Given the input record:

```json
{
  "original_value": 10,
  "other_field": "some_value"
}
```

The output record will be:

```json
{
  "original_value": 10,
  "other_field": "some_value",
  "multiplied_value": 25
}
```
