probably very simple question but yeah, dont know how of course.
I have 3 columns:
A B C
-------
5 1 A
5 2 B
5 3 C
and want to multiply column A and B, and just copy C column. All with one expresion. So Result of multiplication A and B should be in D and result of copying should be in F:
Final result should be:
D F
---
5 A
10 B
15 C
Is there any simple method to do something like this?
