The advantages of Latin when studying mathematics and logic? I'm starting university soon and I'm going to major in math, and minor, at least, in philosophy. I'm also going to start a new language (I'm Finnish and I'm fluent in English), and the languages I've been thinking are Latin and French. I know that if you study a lot of philosophy, it's good to know Latin so that you can read the classics in their original language, but if I'm going to mostly focus in logic (and philosophy of language, but mostly logic), how much good does learning Latin do? Of course learning a new language is never a bad thing, but does knowing Latin help at all when studying mathematics and logic? In mathematics and logic I'd imagine there isn't that much that can be lost in translation.
If you're interested in history of mathematics, then Latin would very likely be helpful; until the 18th century or so, most mathematics done in Europe was written in Latin.

For studying modern mathematics, Latin isn't so useful.  I'm a mathematician and have studied a little Latin, and it hasn't really been directly useful.  Sometimes it helps a little in understanding a word's roots, but not much beyond that.

On the other hand, I do fairly often need to read a paper in French; there's a signficant amount of current and recent mathematics research written in French.  However, this isn't too hard even though I've never formally studied French.  The vocabulary and language used in mathematical writing, while specialized, is quite limited.  And I know some Spanish, which is helpful in figuring out the grammar where needed.  

So for mathematics, neither one is strictly needed, but given the choice I'd choose French.
