Little Professor

The Little Professor is a backwards calculator designed for children ages 5 to 9. Instead of providing the answer to a mathematical expression entered by the user, it generates unsolved expressions and prompts the user for the answer.

When the user turns the Little Professor on and selects a difficulty level, an incomplete equation such as “3 x 6 =” appears on the LED screen. The user has three chances to enter the correct number. If the answer is incorrect, the screen displays “EEE”. After the third wrong answer, the correct answer is displayed. If the answer supplied is correct, the Little Professor goes to the next equation. The Little Professor displays the number of correct first answers after each set of 10 problems.
