This sounds like a recursive homework problem.

Write a recursive function.
When descending the tree,
- if the node is an integer, return it
- if the node is a list, take the operator, recurse into the children, then evaluate the operator, and return the evaluated list
When evaluating the operator, the evaluated argument nodes are either values or lists with the value in the first entry

I'm a complete beginner at this and have no clue how to do any of that. There isn't really much material online to help figure this out. Any chance you could give me a bit more of a push in the right direction on how to do that?

Thanks,
