The **subtract ( -)** operator allows you to subtract two numbers and return their difference.

`number - number subtract(number, number) number.subtract(number)`

When used in mathematical equations, the `-`

operator follows the standard mathematical order of operations (PEMDAS). For more detail, see Operator Precedence.

You can also use the function version, `subtract()`

.

## Example Formulas

```
12 - 5 /* Output: 7 */
subtract(5, 12) /* Output: -7 */
12.subtract(5) /* Output: -7 */
```

### Working with 3 or More Operands

Since **subtract** is a binary operator, it can only work on two *operands –* the objects which are being operated on (if – the *ternary operator – *is the only operator that works on three operands).

If you need to work with more than two operands, the shorthand `-`

is by far the easiest way to do it.

```
40 - 10 - 5 /* Output: 25 */
subtract(subtract(40, 10), 5) /* Output: 25 */
40.subtract(10).subtract(5) /* Output: 25 */
```

## Example Database

The example database below tracks a weekend of treasure-spending by three pirates. Each starts with a **Start Budget** of $3,000, and the **Leftover** formula shows how much each has left after the weekend.

### View and Duplicate Database

Note how I’ve set the **number format** of each column to **U.S. Dollar.** I’ve also set each column’s **Calculate** value to **Sum,** allowing me to see the total of all rows put together.

### “Leftover” Property Formula

```
prop("Start Budget") - prop("Saturday") - prop("Sunday")
```

Instead of using hard-coded numbers, I’ve called in each property using the `prop()`

function.
