Hello , I have some questions about Korean grammar, could you guys give me a hand,plz ?
Ok,my questions are:
1) I get so confused about the usage of 나가다 and 나오다, also 들어가다 and 들어오다,so could you explain their usage further to me?
2) There's a sentence saying:우리 가족이 네 명입니다. But there's another one saying : 남동생이 한 명 있습니다.So what's the difference between these two usages,and does it matter if I switch them?
3) What is the differnce between the final ending -을까요/ㄹ까요 and -읍시다/-ㅂ시다? Is the latter more formal than the former,or is there a difference in the meaning?
4) And the last one,please tell me the differnce between 가다 and 오다,does the usage depend on the speaker's position?
Please help me,thank you so muchhhh.And have a good day
