How to calculate sum of each list?

First, I have two list, I have a desired to calculate sum of “0 List”, and be similar for “1 List”…But I don’t know any idea to solve this now.
seconds, how can I address if I have n list like this?
I hope get lots of your sharing, thanks you! :blush:

hope it helps!
just use the Math.Sum node using the level you need!


Thanks a lots Mauro :wink:

Thank you!

I am wonder why I have the Math.Sum as double as output parameter instead of the word “sum”. Because the Math.Sum doesn’t calculate the sum, only it show a list of double numbers.
