Arithmetic

Arithmetic expressions operate on numbers and produce a result that can be stored in a constant or variable.

Operator	Description
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (remainder)

const sum = 10 + 5
const difference = 10 - 5
const product = 10 * 5
const quotient = 10 / 5
const remainder = 10 % 3

Both operands can be variables:

@a = 10
@b = 3
const result = @a % @b

Assignment

Assignment operators modify a variable in place.

Operator	Description
=	Set value
+=	Add to
-=	Subtract from
*=	Multiply by
/=	Divide by

@n = 10
@n += 5
@n -= 2
@n *= 3
@n /= 2

Array append

When used on an array variable, += appends an item rather than performing numeric addition.

@items: array
@items += "first"
@items += "second"

Conditional and logical operators

Conditional operators (==, !=, contains, >, etc.) and logical operators (&&, ||) are used in if statements and are covered in Control Flow.
