Operators

Operators can be placed into three categories—binary, unary, and ternary. Binary operators, most commonly associated with the concept of operator, take two (binary) expressions and combine them into a third complex or compound expression. However, a single expression can have several binary operators. For example, the following variable declaration uses multiple binary operators to define the variable:

						var calcAdd = (total / n ) + 73 

The divide (/) operator and the plus (+) operator are binary operators. The first combination occurs when the variable total is divided by the variable n. The two variables become a single value. That single value resulting from total divided by n is then added to the literal numeric value of 73, creating ...
