+ File Name: 11.6.2-1.js
+ ECMA Section: 11.6.2 The Subtraction operator ( - )
+ Description:
+
+ The production AdditiveExpression : AdditiveExpression -
+ MultiplicativeExpression is evaluated as follows:
+
+ 1. Evaluate AdditiveExpression.
+ 2. Call GetValue(Result(1)).
+ 3. Evaluate MultiplicativeExpression.
+ 4. Call GetValue(Result(3)).
+ 5. Call ToNumber(Result(2)).
+ 6. Call ToNumber(Result(4)).
+ 7. Apply the subtraction operation to Result(5) and Result(6). See the
+ discussion below (11.6.3).
+ 8. Return Result(7).
