There is a way call square and multiply can it be used to solve the question?

comment How does one calculate the scalar multiplication on elliptic curves?
Yes, this is what I want, so do you mean to calculate 200P, first I convert it into binary to get 2^7 +2^6 +2^3, then next form this dbl(dbl(dbl(dbl(dbl(dbl(dbl(P)))))))+dbl(dbl(dbl(dbl(dbl(dbl(P))))))+dbl(dbl(dbl‌​(P)), until this part I can understand. Thanks for the example, and then next I need to calculate dbl(P) then dbl(dbl(P)) again untill dbl(dbl(dbl(dbl(dbl(dbl(dbl(P))))))) seven times?

I don't understand how to do scalar multiplication said above example, P = (16,5) I know using doubling to get 2P value. But when doing encryption, given random value k said 200, how to count kP= (x,y). Like your example, how did you get all (7,3) (18,10) (10,16) ... this is the part I can't figure out.

I know how to count 2P but if said the k is big said 200P ?
