| `numeric - numeric` | `numeric` |
| `duration - duration` | `duration` |
| `currency - currency` | `currency` |

## Multiplication (*)

### Description

Calculates the product of two values.

### Syntax

`<Numeric field or Expression> * <Numeric field or Expression>`

### Supported values

## Division (/)

### Description

Calculates the quotient of two values.

The first value is divided by the second value.

### Syntax

`X / NULL` will return `NULL`.

### Example

`Throughput time / Number of events`

## Percentage

### Description

Calculates the percentage of two values.
