Summation of particular columns


Hello everyone,
i'm currently looking for an Operator which can do the following:
Col1 | Col2 | Col3 | Col4 | ... | Col-N
...
->
Col1 | Col2 | Col3 | Col4 | ... | Col-N | Col4 + Col5 + Col19 |
The columns only contain numbers. How can i realize this? Which Operator is suitable for this task?
greetings
