# `+` — Conjugate / Add

Function. Ranks: `0` monadic, `0 0` dyadic

`+Y` conjugates. Pervasive.

``` bpl
+2j3              ⍝ 2j¯3
```

`X+Y` adds, with leading agreement.

``` bpl
2+3               ⍝ 5
10+1 2 3          ⍝ 11 12 13
```

Character offsets are integral Unicode code-point offsets.

``` bpl
'a'+3             ⍝ 'd'
```

## Inverse

`+⁻¹Y` is `+Y`. With either argument fixed, `+⁻¹` subtracts the fixed
argument.

``` bpl
3+⁻¹10   ⍝ 7
```
