Answer

Personally, I learned some everyday phrases at first. Then, I took Hangul. Everyone think it's very hard to learn it, but if you deal with it, all further learning become easier. I recommend you to start from it :)
It's like a basis for a language. What will you start from : getting to know mathematic rules and theories or numbers? ;)
