## The * arithmetic operator

### Syntax

```
expression * expression
```

The * arithmetic operator basically multiplies the expressions.

It can multiply the expressions on either side of the operator.

The * arithmetic operator is a synonym for another Envision Basic command, REM. REM creates a comment line.

You must include the REUSE function to apply arithmetic operations to all elements of a dynamic array.

### Example

```
OUTPUT.DATA = V.VAR1 * V.VAR2
```

The *= arithmetic operator multiplies the value of a variable by the specified number.

Using *= operator is more efficient since it’s less code. For e.g. *VAR *= 2* is better then *VAR = VAR * 2 *

You must include the REUSE function to apply arithmetic operations to all elements of a dynamic array.

### Example

```
VAR1 = 10
