The skills of addition and subtraction to 10 with the help of interactive simulators in mathematics contributes to the training of preschool children for school.

Mathematics is a phenomenon of human culture. Joining her is first of all the introduction to the imperishable cultural values, and thus, its role in the development of the personality of the growing human extremely important. In addition, the well-being of this person depends on the adequacy of its behavior in modern society, its readiness to exist in society. Mathematics is one of the most important fields of modern man. Widespread widespread use of technology, including computer, demands a certain level of mathematical knowledge and views.

From early childhood to old age, we are in one way or another are connected with mathematics (even dial a phone number requires knowledge of numbers and the ability to memorize digital sequence). The child is faced with mathematics in early childhood, mathematics needed and housewife (otherwise it is reasonable to build your budget will include a microwave, washing machine, choose the appropriate Bank and so on), and the carpenter, and businessman and a scientist, dealing with the problems of the universe and society.

Arithmetic or arithmetics (from the Greek word ἀριθμός, arithmos "number") is the oldest and most elementary branch of mathematics (compared to algebra, geometry, and analysis). It consists in the study of numbers, especially the properties of the traditional operations between them — addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory. However the terms arithmetic and higher arithmetic were used until the beginning of 20th century as synonyms for number theory, and are, sometimes, still used to refer to a wider part of number theory

The prehistory of arithmetic is limited to a small number of artifacts which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed.

The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but the characteristics of the particular numeral system strongly influence the complexity of the methods. The hieroglyphic system for Egyptian numerals, like the later Roman numerals, descended from tally marks used for counting. In both cases, this origin resulted in values that used a decimal base but did not include positional notation. Complex calculations with Roman numerals required the assistance of a counting board or the Roman abacus to obtain the results.

Early number systems that included positional notation were not decimal, including the sexagesimal (base 60) system for Babylonian numerals and the vigesimal (base 20) system that defined Maya numerals. Because of this place-value concept, the ability to reuse the same digits for different values contributed to simpler and more efficient methods of calculation.

The continuous historical development of modern arithmetic starts with the Hellenistic civilization of ancient Greece, although it originated much later than the Babylonian and Egyptian examples. Prior to the works of Euclid around 300 BC, Greek studies in mathematics overlapped with philosophical and mystical beliefs. For example, Nicomachus summarized the viewpoint of the earlier Pythagorean approach to numbers, and their relationships to each other, in his Introduction to Arithmetic.
