Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_nA7X):
Calculate ( 9 + -9 ).

Question 1 (Question id: q_VkQhG):
Calculate -1 * -9.

Question 2 (Question id: q_GK2TGK3):
Calculate -8 + 2 * 9.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered – number you actually answered.

Also include 'combined_results' consisting of:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
