I think if you had spent as much time looking in your book for HOW to do these as you did TYPING them, you'd be almost done by now (and you'd have a good idea WHY you work them the way you do).
And since this is in HOMESCHOOLING, go ask your teacher for more help.

You need to ask your teacher for help or get yourself a tutor. If you would look at your textbook a little more closely, you should find examples in it and be able to follow the examples to solve the questions yourself.
