# 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.
