Types of Operators
Arithmetic operators take numerical values (either literals or variables) as their oper-
ands and return a single numerical value. The standard arithmetic operators are addition
(+), subtraction (-), multiplication (*), and division (/). See Table 5.2.

Subtraction
x * y
Multiplication
Division
a
x / y
x % y

a. The / operator returns a floating-point division in JavaScript, not a truncated division as it does in languages
such as C or Java. For example, 1/2 returns 0.5 in JavaScript and 1/2 returns 0 in Java.
