I was looking at this question and i can`t understand this part:
QA = dA G
= 5 (5,1)
= (9,16)
I saw that algorithm used for this was Double-and-add algorithm but i didn't get it. Can anyone explain how can i do this calculation on papir?

@FilipFilipovic Does the linked question answer your question in a satisfactory manner? – Ella Rose Jul 29 '19 at 21:04

I've closed the question (putting it on hold) as you've indicated that the other Q/A already explains your problem. If you have any remaining / followup question it is probably best to create a new one. And welcome to crypto, of course :) – Maarten Bodewes Jul 29 '19 at 23:27
