For the product of random variables, there are close form solutions for some common distributions, but I guess Monte-Carlo simulations are all you need in practice (+ with Monte-Carlo can always have the whole distribution, not just the expected value).
Quick convenient monte carlo sim UI seems tractable & neglected & impactful. Like you could reply to a tweet with “hello you are talking about an X=A*B*C thing here. Here’s a histogram of X for your implied distributions of A,B,C” or whatever.

Oh sweet
