Im not understanding at all

Answer 1

Okorie Chibuike, I would recommend you to start learning coding with python. Use the sololearn tuturial and work through it. Do also simple codes in playground to practice what you have learned. I you get stuck with a question or with a code, come back here and post your question, so that we can help. Please keep in mind, that it takes time to understand coding and all the stuff around. If you get more familiar with the basics, you can see that things will make progress and motivate you.

Answer 2

There are for example operators such as +, -, *, / etc.

Answer 3

May be you could give us a more precise question, so that we can help you? Thanks!

Answer 4

"operators" do operation with values... they are convenient ways to do things without the use of most verbose and less natural (for usual operation) function definition and call syntax ;)
