Arithmetic Operations

A typical arithmetic operation operates on two numbers to produce a new number. The two numbers can be:

literals: var x = 100 + 50; (The value of x is 150)
or variables: var a = 100, b = 50, x = a + b; (The value of x is 150)
or expressions: var a = 3, x = (100 + 50) * a; (The value of x is 450)
