This is not an ordinary and boring collection of mathematics tasks for students in grades 1 and 2, but a fascinating and visual aid for children who only learn to count. Each task is accompanied by large illustrations and detailed explanations, schemes and tables that help the child and understand what is required of him and solve the task. Tasks and examples are more complicated from the beginning of the book to its end: first you need to master the mark of numbers and determine the number by image and only then fold, subtract, multiply and divide, and also find the difference in weight, in price or in quantity.
