The best stimulus to learn mental arithmetic. With this unique math trainer, children learn mental arithmetic in a fun way.
The device does not perform calculations, but gives the student a sum based on: multiplication, division, addition or subtraction. The device then checks the result. A 'happy' or 'sad' professor in the window indicates whether the answer is 'right' or 'wrong'. You will receive a 'star' for every correct answer and a 'smile' if 5 problems are solved correctly.
This unique math trainer has four basic operations: addition, subtraction, multiplication and division. There are five difficulty levels that can be set individually: from level 1 (very easy) to 5 (very difficult). The training calculator has more than 50,000 pre-programmed exercises.
The Texas Instruments TI Little Professor Solar Training Calculator has a robust housing and works on solar cells.
