You can put this solution on YOUR website!
you are correct. As for why the -23 stays -23... look at my Lesson on "Signs". I have one for addition/subtraction and one for multiplication/division. They tell you the simple rules too.

Not too sure what you want me to say on the second part, sorry. Look at my Lessons though and i hope they help you.

Good luck.

Jon.
