```
++2⊸=∧=⟜2
```
This utilizes the "3-train"- any functions in the form `w fgh x` is turned into `(w f x) g (w h x)`.

In this case, `2⊸=` and `=⟜2` are functions that check if the right and left arguments are equal to `2` respectively, `and`ed together with `∧`. This is `1` if so, `0` if not.

`+` is the function to add numbers together.
```
+                 +          (2⊸=        ∧    =⟜2     )
sum of the args   added to   (right = 2  and  left = 2)
```
