The book is designed as a workbook and is intended to introduce preschool-aged children to the arithmetic operations of "addition" and "subtraction", the concepts of "set, composition of a number, forward and reverse counting, units and tens, equality and inequality". By solving the first math problems, the child also develops curiosity, attention, logic, memory, and trains hand motor skills.
