*Balloon Ride





   This is the true test for X-zone voyagers.  The students are now back on earth and must solve problems without help from the orbs, Ots, or Fad.

   The full version of the X-zone has 4 skills programmed for Balloon Ride:
      Addition of Integers
      Integer Subtraction and Addition
      Multiplication and Division of Integers
      Simplifying Algebraic Expressions

   Each skill in the licensed version has 99 levels of difficulty!  To our knowledge, no earthling has made it past level 49.  The shareware program is limited to 10 problems at levels 2 and 3.

*How to play





   Five hot air balloons are falling slowly from the sky.  To keep them in the air and score points, you must type the answers to the problems beneath each of the balloons.
   Only one problem will appear at a time.  Click your mouse under a falling balloon to make another problem appear.  Type your answer, and the balloon will rise if you are correct.  You may also use the right or left arrow key on you keyboard to go to another balloon.
