The above example presents a rule, that assigns the numerical value ''20'' to the (numerical) question ''Average value?'' in the case that "numerical question" is greater than 0.

!!Combining Rules
Using such rules, we often not only want something to happen if the condition is true (e.g. temperature <= 0), but also when the condition is false. We can of course always do this, by writing a second rule, using the negated condition of the first rule (temperature > 0). With d3web KnowWE, we provide the possibility, to just use the keyword ELSE, similar to how it is known and done in software engineering.
