1.6 Operators and Precedence

VB supports the following operators:

Operator	Description
+	Addition, string concatenation
+=	Increment and assign
-	Subtraction, unary operator
-=	Subtract and assign
/	Division
/=	Divide and assign
\	Integer division (no remainder)
\=	Integer division and assignment
Mod	Modulo arithmetic
*	Multiplication
*=	Multiply and assign
^	Exponentiation
^=	Exponentiation and assignment
&	String concatenation
&=	String concatenation and assignment
=	Equality, assignment
Is	Equality (for object references)
<	Less than
<=, =<	Less than or equal to
>	Greater than
>=, =>	Greater than or equal to
<>, ><	Not equal to
And	Logical or bitwise conjunction
AndAlso	Logical conjunction with short-circuiting
Or	Logical or bitwise disjunction
OrElse	Logical disjunction with short-circuiting
Not	Logical or bitwise negation
Xor	Logical or bitwise exclusion

Expressions are evaluated in the following order:

1.       Arithmetic operators

a.       Exponentiation

b.       Division and multiplication

c.       Integer division

d.       Modulo arithmetic

e.       Addition and subtraction

2.       Concatenation operators

3.       Logical operators

a.       Not

b.       And, AndAlso

c.       Or, OrElse

d.       X

If two or more operators in an expression have the same order of precedence, they are evaluated from left to right.
