ROBO.
ROBO is an addition program I wrote for my seven year old daughter, Amy.
It presents the learner with a number line (lamentably a bit too small for
the entire range of values generated) and with random pairs of numbers to
add together.  It gives a bit of positive feedback for correct answers and
four opportunities to guess or calculate the right answer before giving up
and presenting a brand new problem.  At the end of the program the total
number of right and wrong answers are presented and the student is encour-
aged to run the program again.

The numbers generated are all integers.  With a bit of modification, the
program can be made to generate negative integers or real numbers for more
advanced students.
