A full range of mathematical operations can be used in association with functions. Mathematical operations return numbers as results. If any non-numeric values are subjected to mathematical operations (for example, a string), the non-numeric value is returned unmodified. Calculations that contain more than one arithmetic operation use the standard order of operations. For example, the calculation ${10+15*3-5} returns a value of 50.

## Example

The custom attribute (**AtbNumber**) is assigned a numeric data type.

When the value stored in **AtbNumber** is **5**, the following function returns a numeric value of 15:

`<%${user.CustomAttribute['AtbNumber']*4-5}%>`
