Hey all,

This is my first post on the forum. I have been looking for the answer for hours but alas.

Here is the thing.

I have two lists of points and i want to subtract the second list from the first list but according to the right index.

so from the first list @L3 = index 0 I want to subtract the value of the second list at index 0@L2, then from the first list @L3, index 1 i want to subtract the value of the second list at index 1@L2. Then those matching items should be deleted in list 1

Please help or tell me if i ain’t clear.
