Arithmetic Operators

a + b a is added to b
a - b b is subtracted from a
a / b a is divided by b
a % b Gets remainder of a by dividing with b

| a * b | a is multiplied with b |

let (a, b) = (4, 5);
let sum: i32 = a + b;            // => 9
let subtractions: i32 = a - b;   // => -1
let multiplication: i32 = a * b; // => 20
let division: i32 = a / b;       // => 0
let modulus: i32 = a % b;        // => 4
