từ 1 đến 9 cần số cs là:

[(9-1):1+1]x1=9(cs)

từ 10 đến 99 cần số cs là:

[(99-10):1+1]x2=180(cs)

từ 100 đến 985 cần số cs là:

[(985-100):1+1]x3=2658(cs)

từ 1 đến 985 cần số cs là:

9+180+2658=2847(cs)

đs: 2847 cs

Từ 1 --> 9 có 9 số

Từ 10 --> 99 có: (99 - 10) :1 + 1 = 90 số

Từ 100 --> 985 có: (985 - 100) : 1 +1 = 886 số

Để đánh số trang của cuốn sách dày 985 trang người ta dùng tất cả : 9 + (90 x 2) + (886 x 3) = 2847 (chữ số)

Dear Liu!

Last time I told you that I had been thinking about pursuing higher education in the UK. I got started to learn the process of applying for a university in London some time ago. Now I have some questions for you. 

First, what is the procedure for applying for a student visa? Of course. I have to submit an application but what other documents are required? How long does it take me to obtain my student visa? It is important to plan time to wait for visa processing because the time between finding out I have been accepted to go and leaving may be very close together. Second, do 1 have to present my financial documents; for example proof of funds, to prove that I am able to pay for my education? And last, do I need to obtain the International Certificate of Vaccination? Is it required that I have certain vaccinations before I go? What are they? After all. can you make me a checklist: what I should bring and what I should leave at home? 

I wish you and your family the best. I look forward to hearing from you soon. 

                                                                                                     Regards,
