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.

[[-40, -50], [-20, -28, -31, 19], [23, -6, -38, -39], [-11, -19, 27, 44]]
[2000, -329840, -204516, 248292]
