Division()

Method Summary

Value	evaluate() Checks that arithmetic operators are not applied to boolean operands in Java/C#
void	explain(java.util.Vector explanation, java.util.Vector errors) Textually explains the evaluation of the tree - as opposed to graphical explanation by the view
void	getLocalLearningObjectives(java.util.Vector learnObjVector) Overrides Arithmetic.getLocalLearningObjectives() Accounts for Divide By Zero errors, Correct answer being due to Integer or Real division, and Coercion.
