Would it be possible for some amazing kind person to write the script for me? I can't code.
What kind of script? You can calculate the addition of those public keys really easily. Just take a program, such as Secp256k1 Calculator and fill the proper fields.

Once you add those two points:
Code:
x: 4BDC661EFDC05C536E1E116B9E059D0E36AA3A25253E18DFC0DDEFD4FACF36F3
y: 22D570A7D46E4F19E3D94869FEF6894ADFA93771837F36B03D3E8341FB15B62C

x: 05FC50574C83CC70A20BDE37F637F76EC53F7780A8FE6C4A4EA7EE9641FD5D39
y: C9523862EBE583E5A9B1423DDC54C789EB332DD9D30A2939CB10258D88987C1F

You'll get this one as a result:
Code:
x: 937192A2BA413909EA6AED1CA53E0AA294736BBB6F41164D159E0A7392926C00
y: 56AFE970031AD898FE0AAD818C133E131122EE682E8FF9C3F1DAB493754999EF

Since it returns you coordinates, it's not outside the curve.

Thanks so much, but I wanted to know if, during the calculation, it had to go past "0" to calculate the result like in the image I attached in my first post.

I think I was using the wrong language by saying outside of the field or curve.

I know that the addition always results in a valid point, but did it have to go "around the clock" to get there?

I am trying to show the results in my school project so the Python script (or something) would be fantastic to show it in action.

Thanks again.
