The arithmetic operators are summarized in Fig. 3.19. The asterisk (*) indicates multiplication, and the keyword `Mod` represents the `Mod`
operator (also known as the modulus or modulo operator), which will be discussed shortly. Most of the arithmetic operators in Fig. 3.19 are binary operators. For example, the expression `sum + value` contains the binary operator `+` and the two operands `sum` and `value`. Visual Basic also provides unary operators that take only one operand. For example, unary versions of plus (`+`) and minus (`–`) are provided, so that programmers can write expressions such as `+`9 and `–`19.
