Little Professor 26-82-RC1
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.
Compared with the early Little Professor with the LED display this one uses a LCD to ask the child one of thousands pre-programmed math questions.
Instead of the membrane keys introduced few years ago with the Little Professor (1982) in the United States, this one followed the Little Professor (UK) developed in Europe and uses again normal keys. The technology of the keyboard is identical to well known scientific calculator. Compare it with the TI-30.
