Hi peterhui50
It's not quite as simple as in R I'm afraid, but you can use List.Zip to combine corresponding elements from a list of lists, then perform operations on the resulting list.

List.Transform( List.Zip( {[Numbers_1_3_5], [Numbers_2_4_6]} ), each _{1}-_{0})Regards,

You could also create a virtual table and add a custom column:
Table.AddColumn(
Table.FromColumns({[Numbers_1_3_5], [Numbers_2_4_6]}, {"135", "246"}),
"Diff", each [246] - [135]
)[Diff]This returns the custom column from the virtual table.
