How it works:
Make a selection from the menu for the game you want to play.
Adding and subtracting decimal numbers, play at your own pace.
Adding and subtracting decimal numbers, play against the clock.

Multiplying and dividing decimal numbers, play against the clock.
In the play at your own pace mode, click on the Help button for
a step-by-step guide on how to solve the mathematical expression (multiplication only).
By clicking on the "x and ÷" button, you can choose only multiplication problems, only division problems or a combination of both.
The same function has "+ and -" button.
In the play against the clock mode, you have 10 minutes to solve as many problems as possible.
After 10 minutes, 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 10 correct answers and 5 incorrect answers, the player's skill level rating would be 5.
Skill Level Ratings
Skill level rating based on the number of correct minus the number of incorrect answers:
***** exceptional 12 or more
**** outstanding 10-11
*** superior 8-9
** excellent 6-7
* very good 4-5
To exit the game, click the "MENU" button and then click "EXIT".
All calculations will be saved in a file labeled "decimals.htm" in the "math"
folder on your external memory card or internal storage.
If you are unable to open the file "decimals.htm", you may need to download "Open in Browser"(Denis Nelubin).
The file "decimals.htm" contains the scoring results of the game:
- Correct answers are shown in green text; incorrect answers are shown in red text.
- If the answer was incorrect, the correct answer will be shown in gray text.
- If the Help button was used, "with help" will be shown in gray text.
