Formulas are constructed by stringing together operators, values and functions in a way that a single value results from them. Literal values, fields, and mathematical functions all result in one value, while linking relation functions can result in multiple values, depending on the number of issues that are involved. Operators or aggregating functions reduce multiple values into one. A formula must result in a single value, so subtasks('Quantity') is invalid, but sum(subtasks('Quantity')) is valid.
...
To use a custom field, type its name, for example Budget or Quantity. If your field’s name contains spaces, you must surround it with double quotes, for example “Story Points”. Quotes are optional for values without spaces.
Operators
Operators combine two values. The following operators are supported:
...
Functions are versatile, we provide three types of them. One type consists of mathematical functions, to enable more calculations you can do. The second are aggregating functions, where you combine multiple values into one. The third type fetches values from other related issues.
