Although the rear of the unit describes it as an electronic calculator, you can't use it in the sense of a traditional calculator. Punching in an equation such as 99x9 and then pressing the '=' key will not give you an answer. You must provide the answer yourself by typing in '891'. If you answer correctly, you're rewarded with a little light show on the display. If you answer incorrectly, you're given an error display and prompted with the equation again. Answer incorrectly for the second time, and Dataman will give you the right answer.
In addition to quizing yourself with equations, there are five games that you can play:
Electro Flash- You are prompted to solve addition, subtraction, multiplication, or division problems while a timer runs.
[?]- No title, just the symbols on the key. The timer runs while you solve equations. The user can choose which part of the equation that they want to solve for.
Wipe Out- Looks the same as 'Electro Flash' to me.
Number Guesser- Try to guess the secret number in the fewest guesses.
Force Out- Try to subtract numbers to get to zero in the fewest tries.
Manual is easily obtained online :D
