You have 28 different two-sided puzzle cards from numbers 0-9 and tokens (+ - <> =). In total, you can invoice from 0 to 20. Put Qobo on the starting line and we'll start learning math. Qobo knows the numbers and signs, and when he gets to the end of the task, he'll tell you if you had the right answer or if you need to try again. The robot itself does not predict the correct answer. It is possible to calculate with numbers from zero. You cannot calculate with negative numbers. And most importantly - by ordering from Robomik, educational institutions will receive the Qobo math package in Estonian. Qobo with Estonian sound is protected by copyright. Modification, copying and distribution of sound without the permission of Robomik is not allowed. Qobo - Your faithful companion in learning and playing!
