Point with point to concatenate

abc+def = 18AB
one new func could be inside
like abc+def = abcdef
like point +point = pp ( line extended) ( not 2p)

abc

here abc is 1 point, and 2nd point is def
if we can join or merge like abc add to def
where result would be abcdef point
have you study and experiance this
maybe some help here

point 1
point 2
a =1+2 = 3
more advance looking func

point 1
point 2
a =1+2 = 12

My answer is exactly the same as AntonKueltz's from fastecdsa: I fail to see the usefulness of it in a cryptographic library. If you want to play around with elliptic curve maths, you can do it in your own repo.

The presentation you linked just discusses basics of EC, it doesn't talk about the operation you're looking for.

exactly same Question in my mind,
normal we see func add, double, sub, multiply, div etc
when this link pass from my eye's

Adding points is not the same addition as 1+1=2.

this line make me thinking, if 1+1 =2 is not then ?
then 2nd level Q in mind is 1+1 = 11
if his purpose is 11 then what to use, and where to use,

rest his thheory unable to understand, you are coders, and best to explain us, about whats his mean and detail will help us to understand
Thankx
