Whilst arguing that uncertainty is best measured using numbers and probabilities:
We want to measure uncertainties in order to combine them. A politician said that he preferred adverbs to numbers. Unfortunately it is difficult to combine adverbs.
[missing the point] On the contrary, combining adverbs is easy. If X is very uncertain, and Y is very uncertain, then X—Y is very, very uncertain.

Why isn’t it “very, very uncertain, uncertain”? Anyway, ‘very’ is an adjective. ‘Verily’ is the adverb.
But without the math to prove it, you may wrongly conclude that the uncertainties cancel out and X—Y is quite certain indeed.
