# Ring Operator (`∘`)

## `𝔽∘𝔾 𝕩`: Atop

Apply `𝔾` to `𝕩`, then apply `𝔽` (`𝔽 𝔾 𝕩`).

`𝔽` and `𝔾` must be monadic.

           -∘- 5

           - - 5



## `𝕨 𝔽∘𝔾 𝕩`: Dyadic Atop

Apply `𝔾` to `𝕨` and `𝕩`, then apply `𝔽` (`𝔽 (𝕨 𝔾 𝕩)`).

`𝔽` must be monadic, and `𝔾` must be dyadic.

           1 -∘+ 2

           1 - + 2

           - 1 + 2
