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

***** exceptional 28 or more
**** outstanding 24-27
*** superior 20-23
** excellent 15-19
* very good 10-14
good 5-10

To exit the game, click the "MENU" button and then click "EXIT".

All calculations will be saved in a file labeled "plus&minus.htm" in the "math"
folder on your external memory card or internal storage.
If you are unable to open the file "plus&minus.htm", you may need to download "Open in Browser"(Denis Nelubin) and "ES File Explorer" .
With the saved calculations this is a great tool for giving homeworks.
