You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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

New input: [[31, 1, -26], [-35, 46], [-10, -21, -26, -40, 6]]
Solution:
[-806, -1610, 1310400]
