Math? I don’t think that rpg talks about computing an integral or spending 2h arguing on whether we’re on a Gilbert space and can compute a scalar product.
Ah, but you see, arithmetic is scary.
The only time I get too much to deal with is when I’m rolling four dice per attack, twice per round, and want to have a high level of confidence in my answer while also not taking up everyone’s time. For that I just made a spreadsheet and moved on with it.
You just need to skill in arithmancy. When you need to calculate something in game, roll a check and if you roll high enough the DM has to do the math for you.
