Arithmetic operators
The arithmetic operators are all used to calculate a numeric value, and are normally used in conjunction with the assignment operator and/or one of the comparison operators; they are listed in order of Operator Precedence.

Exponentiation
Raises a number to the power of an exponent.
Result = number ^ exponent
number and exponent is any valid numeric expression.
MsgBox 5 ^ 5
MsgBox displays 3125, which is the result of raising the number 5 to the exponent 5.

Floating Point Division
Returns a floating point result when dividing two numbers.
Result = number1 / number2
number1 and number2 is any valid numeric expression.

Integer Division
Returns the integer part of the result when dividing two numbers.
Result = number1 \ number2
number1 and number2 is any valid numeric expression.
MsgBox 5 \ 4
MsgBox displays
1, which is the integer part of the result, when dividing the number 5
with 4. The numeric expressions are rounded to Byte, Integer, or Long subtype expressions, before the integer division is performed. They are rounded to the smallest possible subtype, i.e. a value of 255 will be rounded to a Byte, and 256 will be rounded to an Integer and so on.

Modulus Division
Returns the remainder when dividing two numbers.
Result = number1 Mod number2
number1 and number2 is any valid numeric expression.
MsgBox 5 Mod 4
MsgBox displays 1, which is the remainder part of the result, when dividing the number 5 with 4.

Addition
Sums two expressions.
Result = expression1 + expression2
expression1 and expression2 is any valid numeric expression.
MsgBox 5 + 5
MsgBox displays 10, which is the result of adding the expression 5 to 5.
If one or both expressions are numeric, the expressions will be summed, but if both expressions are strings, they will be concatenated. This is important to understand, especially if you have a Java background, in order to avoid runtime errors. In general use the &operator (see under Concatenation Operators), when concatenating and the + operator when dealing with numbers.

Subtraction
Subtracts one number from another or indicates the negative value of an expression.
Result = number1 – number2
number1 and number2 is any valid numeric expression.
MsgBox 5 - 4
MsgBox displays 1, which is the result of subtracting the number 4 from 5.
-number
number is any valid numeric expression.
MsgBox -(5 - 4)
MsgBox displays -1, which
is the result of subtracting the number 4 from 5 and using the unary negation
