# Syntax

## Literal Values

Refer to the following syntaxes for using layer names, text, numbers, color values and variables in the formula input field.

##### Layer name

Use backticks around the layer name.

##### Text

Use double quotation marks around the text.

##### Text with multiple lines

Add a \n to add a line break between characters or words.

##### Number

Use Arabic numbers only; other symbols are not allowed.

##### Color

Colors must be expressed in the #FFFFFF format (Hex color code).

##### Variable

Use variable names that do not have any symbols in the name.

## Arithmetic operations

The four basic arithmetic operations (+, -, *, /) and remainder calculations are supported.

### Remainder calculations (%)

Remainder calculations are done to derive the remainder of a division operation by using the % operative. For example, 5%2 would result in 1 as the remainder in that operation is 1.

### Text functions

While arithmetic operations apply to numbers only in most cases, addition can be done with texts. When a text is "added" to another text, the end result is a new text with the two texts combined together. For example, adding "2" to "1" would result in the new text "12".

##### Text + Text

`"helloworld"`

`"12"`

##### Text + Number

`"hello1234"`
