Overview

Internal use only Instantiated by Symbol#coerce or Expression#coerce

x + y is calcurated first and an instance of Expression is created. Then Fixnum#* has no rule when its argument is an instance of Expression so Expression#coerce is called. At last Expression#coerce calls Number#new.

Multiply(Number(5), Plus(Symbol(x), Symbol(y))

Examples:

5*(x + y)
