Math Boffins Help Needed with Pivot

So I didn’t pay enough attention in Maths. Anyone like to help on this one?

The gif shows what I want to achieve. The Fla has the basic components.

I have tried but I can’t crack it. If you want to reply divide the square root of an Acorn by the surface area of a antelopes testicles, multiplied by the resulting mode of a migrating flock of Pigmy ducks, please don’t.

If you can solve the Fla or send an example of something similar. Many Thanks
