public class MiniWrongAssociativity

extends java.lang.Object

This class uses a problematic grammar for Minimath. For a better grammar, see class MinimathCompute. Here, the grammar is:

	
     e = Num '-' e | Num;
 

Writing a parser directly from this grammar will show that the associativity is wrong. For example, this grammar will lead to a parser that calculates the value of 25 - 16 - 9 as 18.
