What is the expiation for the oaths I swore in a moment of anger, the number of which I no longer remember?

Whoever strives to ascertain the number of oaths he has broken and is unable to determine it, he should expiate for the largest number he presumes to be sufficient, and he must exercise caution. If the oaths are multiple and pertain to a single matter, one expiation suffices for them, provided he has not already expiated for the first. However, if the subject matter of the oaths varies, then each oath requires its own expiation.
