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.
One example: [[5, 1, 2, 7], [0, 4, 6, 6], [7, 8, 10, 3, 1], [1, 4]]
Solution is here: [70, 0, 1680, 4]
Explanation: The second list had zero so the second product is zero. Every product is calculated correctly: 5x1x2x7= 70, 7x8x10x3x1=1680, 1x4=4.

Now, solve this: [[31, -33, 16, 0], [36, -49, 46], [47, 29, -40], [5, 23, -46, 43], [-41, 7, 19, 49], [10, -49], [-31, 11, -24], [40, -5, -22, 40]]
Solution:
[0, -81144, -54520, -227470, -267197, -490, 8184, 176000]
