Items in itemize aren't on the text area

Question

Good morning

I've got this source code below. The problem is the item item in itemize isn't in the text area but it's out of the text area. I try to get $$ on every \item line but the result is the same. I have replaced a black ball mark with text. Result is on the picture.

Thank you for help.
