Whenever I need to talk about Bayes’ theorem’s derivation (which is somewhat distinct from its application), I always use form P(A|B)⋅P(B)=P(B|A)⋅P(A) - based on the fact that both are equal to probability of conjunction. It is a bit more robust when putting zeroes in, relative to any division form.
