Upon execution the node will scan the input file to determine number and types of the columns and output a table with the auto-guessed structure and KNIME types. If you wanted to evaluate the same expression for more than one column with the Math Formula node you would need to string several Math Formula nodes together. The Math Formula Multi Column node is an extension of the Math Formula node which evaluates a mathematical expression based on the values in a row for a set of selected columns. 1-3 Download the adultcsv file from the data folder on the KNIME Hub.
