How does one create a math column?

Hello,

How do I learn more about inserting Math into OmniOutliner Pro? I want to do something similar to the Budget Template but can’t find it in the help files.

Thank you.

Make a column. Use the Inspector to set the Type to Number, and Summary to Total.
See this section of the manual:
