Multi-Field Formulas: how to convert several columns of values to the opposite sign

[JokeFun]

I have several columns of data and would like to convert all of them to the opposite sign, say 100 need to be changed to -100. I don't what to write formula for each field to convert. I think the Multi-field Formulas should work. But I don't know which specific formula works here.

Hey @JokeFun 

This should be fairly simple.

Try this:

[_CurrentField_]*-1

I just figured out. This should work.

[_CurrentField_]/-1
