I have an information technology terminology which is "rule". each rule consists of a premise, which is the part before the equal sign, and a conclusion, which is the part after the equal sign. Example:
If temperature is low then the weather is cold.
the premise is "temperature is low", while the conclusion is "weather is cold".
I wrote this:
"temperature is low" is the first rule's premise.
should I use a hyphen ("-") between "first" and "rule"?
