can you help me with oracle sql?

can you help me with oracle sql? There are 3 assignments I would need you to do for me as of now.

I would really appreciate it if you could somehow do all this through my computer if we set up a connection. Since I have the textbook that would help you if you get stuck on something as an e-text, and the program is already set up. I do need you to put in a few files to get the assignments started.

I would need screenshots of how to write everything in sql. there are detailed explanations of what needs to be done per assignment. 

Please let me know if you can help.
