<|system|>Given a definition of a task and a sample input, break the definition into small parts.
Each of those parts will have some instruction. Explain their meaning by showing an example that meets the criteria in the instruction. Use the following format:
Part  # : a key part of the definition.
Usage: Sample response that meets the criteria from the key part. Explain why you think it meets the criteria.<|end|>
<|user|>Definition: In this task you will be given a list of lists, of numbers. For every inner list, you should multiply every number in that list and put the results in your answer. The output should be a list of numbers with the same length as the number of the lists in the input list.
Input: [[7, 18, 37], [20, 34, 21, 6, -14]]
Output:<|end|>
<|assistant|>Part #1: List of lists of numbers
Usage: [[7, 18, 37], [20, 34, 21, 6, -14]]
Explanation: The input consists of a list containing 2 inner lists, each with multiple numbers.

Part #2: Multiply every number in the inner list
Usage: (7*18*37) and (20*34*21*6*(-14))
Explanation: In this step, for each inner list, we multiply its numbers. For the first inner list, the multiplication is 7*18*37, and for the second list, it is 20*34*21*6*(-14).

Part #3: Put the results in the answer
Usage: [4638, -3215520]
Explanation: As per the multiplication results from Part #2, we got the values 4638 and -3215520. These numbers are put together in a new list, which becomes the final output.

Part #4: The output list has the same length as the number of lists in the input list
Usage: The output list has length 2 since there are 2 inner lists in the input.
Explanation: The output list has the same length as the number of inner lists in the input list. In this case, the input list has 2 inner lists, and the output list also has 2 elements - [4638, -3215520].<|endoftext|>
