Dart supports the usual arithmetic operators, as shown in the following table.

| Operator | Meaning |
| --- | --- |
| `+` | Add |
| `-` | Subtract |
| `-expr` | Unary minus, also known as negation (reverse the sign of the expression) |
| `*` | Multiply |
| `/` | Divide |
| `~/` | Divide, returning an integer result |
| `%` | Get the remainder of an integer division (modulo) |

# Example:

```dart
assert(2 + 3 == 5);
assert(2 - 3 == -1);
assert(2 * 3 == 6);
assert(5 / 2 == 2.5); // Result is a double
assert(5 ~/ 2 == 2); // Result is an int
assert(5 % 2 == 1); // Remainder

assert('5/2 = ${5 ~/ 2} r ${5 % 2}' == '5/2 = 2 r 1');
```

Operator	Meaning
`+`	Add
`-`	Subtract
`-expr`	Unary minus, also known as negation (reverse the sign of the expression)
`*`	Multiply
`/`	Divide
`~/`	Divide, returning an integer result
`%`	Get the remainder of an integer division (modulo)
