You seem to not understand these questions you should seek a tutor or ask help from your teacher, it gets a little annoying when people have to answer each and every single one of your questions

Kule sounds a little harsh but I expect he means the same as I meant when I said.

 

Ask one at a time and LEARN from the answer so that you can try the next one on your own.

 

We don't mind helping with lots of questions so long as we feel you are actually learning from our answers.  laugh
