3. Приготовьтесь к беседе о вашей будущей специальности. My Future Speciality

I am a student of the Bratsk State Technical University. My future speciality is connected with the teaching of mathematics and informatics. No problems in physics, mechanics and many other sciences can be solved without mathematics. Every field of mathematics involves different problems. It is an important subject for the students of science. Mathematics sometimes is called “the queen of sciences.” The language of mathematics may be called the language of science. It consists of signs and symbols. Some of the best known symbols of mathematics are the Arabic numerals (1,2,3,4,5,6,7,8,9,0) and the signs of addition (+), subtraction (-), multiplication (x), division (:), equality (=), and the alphabets: Greek, Latin, Gothic. People invented special devices to make computations easier, especially in dealing with large numbers. So modern science is impossible without computers. Computer science is a relatively new and exciting field of study and research. It is a broad discipline covering logic design, the theory of computation, numeral analysis, programming and computer application. That’s why I decided to choose this profession.

Number Systems

Number systems were among the first words used when people began to talk but it has taken thousands of years for people to learn how to use numbers or the written figures which we call “numerals.”

In early days people often counted on a scale of three or four instead of ten and sometimes other number scales were used. Later they found it more convenient to count by tens using the fingers of both hands. We still use this scale in counting: that is, we count to ten; then to ten tens, then to ten times ten tens, and so on.

When people first began to use numbers they knew only one way to work with them: that was to count. Later they found out how to add, subtract and multiply. They invented special devices to make computations easier, especially in dealing with large numbers.

Division was not often needed in ancient times in comparison with multiplication, and it is far more rarely employed than addition and subtraction at the present time.

Besides the decimal number system which we commonly use there are other systems of numeration such as the binary, octal, etc. In the number systems we use digits. The Latin word ''digiti'' means “fingers.”

In ancient times it was very difficult to use fractions because they did not know any easy way of writing them. Decimal fractions were introduced in the 16-th. century and are now much more commonly used than common fractions.
