budding mathematicians. the secret is carefully guiding them with the help of technology. main part using numerals in the classroom numeral systems are a way of representing numbers by a finite type-set of graphical signs called digits. we must add to them the rules for depicting numbers. the characters, which are used to depict numbers in a given numeral system, can be perceived as that system's alphabet. during the different stages of the development of human civilization, various numeral systems had gained popularity. we must note that today the most widely spread one is the arabic numeral system. it uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, as its alphabet. (an interesting fact is that the depiction of arabic numerals in modern times is different from the ten digits mentioned beside an alphabet, every numeral system has a base. the base is a number …

. because of that the binary numeral system is the only one suitable for practical use and it is used in the modern computers and electronic devices [14; 124-p.]. positional numeral systems a positional numeral system is a system, in which the position of the digits is significant for the value of the number. this means that the value of the digits in the number is not strictly defined and depends on which position the given digit is. for example, in the number 351 the digit 1 has a value of 1, while in the number 1024 it has a value of 1000. we must note that the bases of the numeral systems are applicable only with positional numeral systems. in a positional numeral system the number a(p) = (з^уа^у-.а^уа^а^у.-а^) can be represented in the following way: in this sum tm has the meaning of a weight factor for the …

10 l 50 c 100 d 500 m 1000 as we have already mentioned, in this numeral system the position of the digit has no significance for the value of the number and for determining the value, the following rules are applied: 1. if two consecutively represented roman digits are in such order that the value of the first one is bigger or equal to the value of the second one, their values are added [6; 87-p,7;92-p,8;155-p,9;144-p]. example: the number 111=3, but the number mmd=2500. 2. if two consecutively represented roman digits are in increasing order of their values, they are subtracted [25;205-p]. example: the number ix=9, the number mxl=1040, but the number mxxiv=1024. binary numbers the numbers represented in the binary numeral system are represented in a secondary aspect - which means that they are easy to be understood by the computing machine. they are a bit harder to …

thematics education in secondary schools in india has been experiencing reforms directed toward the integration of technology in mathematics courses. despite the mandate that accompanies the education policy document, that computer technology be integrated in the range of courses in the secondary mathematics key learning areas, there is evidence to suggest that computers are not widely integrated into indian secondary mathematics classrooms. the international evidence suggests that one reason for the teachers not embracing technology, is the fear that, it might replace teachers in the school system. other experts attribute the ineffective integration of technology to the lack of adequate knowledge, about when and how computers could be used in mathematics instruction, and lack of adequate level of training. this ineffective integration is obviating the benefits that are expected by integration of technology in the classroom teaching [12;68-p,13;109-p]. teachers role: in a balanced mathematics program, the strategic use of technology …
