Hi @armingrudd,
I think @andersenyunan wants a single column that is derived from multiplying all the other columns. It can be done using the Column Aggregator. Here just select your columns and in the second tab select “Product” from the left list by double clicking on it.

Yes, Maybe. But regarding his example table, it seems the column A values are some kind of factors by which the other values should be multiplied and also he says: “I’m trying to multiply 10-20 column to 1 column”.
But also he says: “I’m looking at math formula node but it’s quite long on the expression”. In this case, I think you are right and the product of all values is desired.

Thanks for the solution! just wondering if the column to multiply is more than 1 could it still work? for instance something like this where the output would be between A to B,C,E,F,G and Z to B,C,E,F,G

Hi @andersenyunan,
so @armingrudd’s solution is the one that is applicable here. I thought you want to calculate the product of all columns. To get a table like the one above, you will need to use two Math Formula (Multi Column) nodes. One for A and one for Z.
Kind regards
Alexander
