The calculate

Hi, all
Is there nodes that can Calculate, like input formulas to calcuate number.

Hi @zero ,

can you please further explain? The request is too general to give a good answer.
You might be looking for a Math Formulas or a Column Expressions node, however.

Have a nice day,

Ok, like the excel I can input the data, then I input the different formula, such as, Multiplicative, additive, and exponential formulas finally. I get the result.

In this case, both nodes proposed can do what you need.
I suggest you watch these videos from the KNIME Basic course:

Have a nice day,


Column Expression node is so often referred to and used as it is indeed a very versatile node.
Is there any documentation, experience on its performance in comparison to other nodes?


Thank you!I will try it.
