rule engine and math operation in outcome


I use KNIME 2.11.1 and tried the rule engine. I really find it more easy to use than Java Snippet for some comparisons but I wonder if this works:

$col3$ LIKE "col1_active" => $col1$ + $col2$

I want to add the values of two colum for the outcome. I get errors and tried several bracket like () and {}.



Mathematical operations are not supported in rules. If you want to perform such complex operations you are better off using the Java Snippet node.
