                 Free Smart Phone App Helps Students With Math

   School children usually can count on their parents to help them check
   if their homework is correct. But as students get older and their
   assignments get more complex, few parents are qualified to assist them.
   At least for mathematics there is a solution, as a Croatian computer
   whiz is responsible for creating an application for solving equations.
   Zlatica Hoke reports the free "app" has had millions of downloads since
   it was launched late last year.
