There are four groups of operators in VB.NET: arithmetic, concatenation, comparison, and logical. We will look at each group of operators in turn before discussing the order of precedence VB.NET uses when it encounters more than one type of operator within an expression.
The arithmetic operators are:
The addition operator. Used to add numeric expressions, as well as to concatenate (join together) two string variables. However, it is preferable to use the concatenation operator with strings to eliminate ambiguity. For example:
result = expression1 + expression2
The subtraction operator. Used to find the difference between two numeric values or expressions, as well as to denote a negative value. Unlike the addition operator, it cannot be used with string variables. For example:
result = expression1 - expression2
The division operator. Returns a floating point number. For example:
result = expression1 / expression2
The multiplication operator. Used to multiply two numerical values. For example:
result = expression1 * expression2
The integer division operator. Performs division on two numeric expressions and returns an integer result (no remainder or decimal places). For example:
result = expression1 \ expression2
Note that regardless of what specific numeric data types
expression2 are, integer division returns only an integral data type (Byte, Short, Integer, or Long). After the division is performed, the result ...
