MathTrax has the ability to sound out the graph being drawn to take understanding one step higher.

For example, if a graph line crosses the same axis twice the auditory visualization will indicate that activity.

Audio playback provides a way to “see” what we would normally not be able to. This particular feature is of great use to the vision impaired community.
