Good Day Experts!

I have a little project going on here that I am looking for a bit of help on.  I have a DataTable that is filled with query results from a SQL query.  Once I fill that DataTable I would like to add a column to the DataTable and then put in the column the value of subtracting 2 columns that were already present in the DataTable.  

I have added the column.  But now how do I subtract two columns in the DataTable and put the results in this new column:

tblGetExportReseachFinal.Columns.Add("Count Remaining", Type.GetType("System.Integer"))

Thanks,

By going through each row and doing that calculation. I don't believe there is an automatic way.
