Subtracting from another cell when data changes

Hello All!
I am trying to have a cell that is reflecting the total of projects I am working on to subtract from another cell whenever that cell is change, reflecting that the project is complete. In the screenshot below I want the Total Cell to Subtract the Completed cell. The formula grabbing other data from this sheet looks like this.
=SUM([Column3]1, [Column3]17) (Total Cell)
=SUM([Column3]10, [Column3]26) (Completed Cell)
Any help would be appreciated!

You would simply subtract one cell from the other
=[Column Name]1 - [Column Name]2
If either or both cells have formulas, you can subtract one formula from the other or even a cell from a formula or the other way around.
=SUM(.....) - SUM(.....)
=SUM(.....) - [Column Name]2
=[Column Name]1 - SUM(.....)
