Math Run

Math Run is labeled a "math training game," and presumably was developed for school or homeschool use rather than as a recreational puzzle per se.

I completed the first 30 levels, but with holiday chores pending, I decided to take a screencap and quit.  Perhaps some reader with time to spare will continue on and let us know at what level the game challenges math skills rather than patience.

The image at right is a screencap.  The Math Run game is here.

A procedural note - in the game the colon symbol (:) is used in place of the backslash forward slash (/) to indicate division.  Where is this a common convention?
