Correct answers are shown in green; incorrect answers are shown in red.

In the play against the clock mode, you have 60 seconds to solve as many inequality expressions as possible.
After 60 seconds, your score and skill level will be displayed. The skill level rating
is calculated by subtracting the player's total number of incorrect answers from
the player's total number of correct answers.
For example, if a player had 27 correct answers and 5 incorrect answers, the
player's skill level rating would be 22.

Skill Level Ratings

**** outstanding 24-27
*** superior 20-23

* very good 10-14
good 5-10
