This book avoids, as much as possible, overcomplicated terms. Nevertheless, the following were deemed important enough that omitting them would be a disservice to the reader.

### Arity
|
||
|
|
|
||
|
|
Arity refers to the number of arguments a function or operation takes.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let x = (2, 3);
|
||
|
|
let y = (4, 6);
|
||
|
|
let z = (8, 2, 6);
|
||
|
|
```
|
||
|
|
|
||
|
|
In the example above `x` and `y` have arity 2. `z` has arity 3.
