I’m trying to do a very basic math function. inside my app, but not sure where to go to find this action.

I want two columns for number entry that the user could put in and the third column would display the difference between those two columns. Any suggestions?

For that type of use case, you will probably want to use [User Specific Columns](https://www.glideapps.com/docs/reference/basic-columns/user-specific-columns). This will allow multiple users to do the same calculation in your App simultaneously.

As @Rosewebstudio and @Darren_Murphy said you can use Math columns with a combination of number input in [User Specific Columns](https://www.glideapps.com/docs/reference/basic-columns/user-specific-columns).

If you need 1 on 1 session you can contact me and we can set up a meeting.
