Below are details about how the expressions work:

Arithmetic expressions relate two operands (which can be any the operands described above, or another expression) to make up the sum, subtraction, multiplication or division.

Relational expressions compare two operands (value/text or other expression) to assess whether a condition is true or false. Normally used with decision functions, such as ''IF''.

Logical expressions group together two operands (Boolean or other expression) to make up a logical expression, in order to evaluate the relationship of two Boolean operators to a true or false result. This type of expression is usually used for decision making, such as IF and with relational expressions.

Basic helper functions are standard system functions and implement useful features for composing complex expressions.
