What do you mean by "original curve point"? Do you mean the generator point? If so, that's part of the curve parameters. You can only know that by knowing what curve you are using and its parameters. Given just a public key, you cannot know the curve parameters.
Using Elliptic Curve of SECP256K1 of bitcoin, I believe with scalar multiplication of
"Point P & Q" we get the
"point R", but the value what we get is hash values but I can convert it to the integer which results in
"77 digits in X and Y coordinate".
I'm trying to learn something that usually in a graph we don't work on large integers, but is there a way to remove the
"generator point hash G" so we can see the actual point values like [0,1] or [10,16] etc.,??
