Hello! I'm trying to perform some simple arithmetic on 3 separate search results so that I can display them on one dashboard. Is there a predefined way to do this?

For Example: Suppose you have 3 numbers from search results 1,000 2,000 and 3,000. I want to be able to display 3,000-2,000. In a new panel with a new label. I was thinking perhaps append? But I am somewhat new to splunk. Thanks again!
