Artificial Intelligence / Unit 5 AI 0248 short lesson, about 20 seconds
And, and If

The idea
The wedge symbol joins claims and reads "and"; the leftward arrow points from conclusion back to conditions and reads "if" — conclusion first, conditions after.
In practice
Head ← body-one and body-two reads: the head, if both bodies hold — the rule form of this unit, now in symbols.
Where people slip
The conclusion-first grammar runs against English habit; both grammars state the same fact.
