EXTORSHEN, I did work it out. I only ask when I think the answer is wrong and made a mistake. When I checked, both #2 and 9 didn't work. Only later, check the first comment, did I see that #9 might be the right answer.
EXTORSHEN thanks for recommending the website btw... but I would like to see a real person do or explain the other questions I had.
CPILL thanks :) love how you explain the steps
