This educational toy is an ideal tool for preschoolers and early school-age children. It works on a simple principle: the child touches one contact to the selected problem and the other to the result—if the calculation is correct, the indicator light turns on. Learning turns into a fun and motivating game that fosters independence and confidence in arithmetic.

The box includes a rich set of problems for addition and subtraction up to 20. The electronic panel with a light indicator provides instant feedback without notebooks or pencils. Requires 2× AA batteries (not included).

• Instant result checking – the light turns on for a correct answer.
• Supports independent learning – children can verify their knowledge without assistance.
• Fun format – playful practice of basic operations up to 20.
• Ideal for home practice and tutoring.
