Hi there @erisu,

you should use Math Formula (Multi Column) node to achieve this. Include columns that need to be multiplied and use this expression:

$$CURRENT_COLUMN$$ * $Column3$

Make sure to check Replace Selected Columns and Convert Selected Columns to Int options at the end of configuration dialog if needed.
