人类经过长期的社会实践,创造出利用少量的名称和记号来表示任意自然数的记数方法.这一方法是位置原则,就是把数字排成横列来表示一个自然数,每一数字除了本身的值以外,还有一个所在位置所赋予的值(位置值).位置原则是数字和数位相结合的原则,马克思高度称赞位置原则是数学上“最美妙的数学发明”.在各类数学竞赛中,与进位制有关的赛题频繁出现,有考查十进制、其它进制、进位制之间相互转换的试题,也有借助二进制数字符号命制的
Through long-term social practice, mankind has created a method of counting natural numbers by using a small number of names and notations, a principle of location that ranks numbers in a row to represent a natural number, with each figure excluding its own value , As well as a value (location value) given by the location.Position principle is the principle of combining numbers and digits, and Marx highly praises the principle that the location is mathematically “the most wonderful mathematical invention.” In various mathematical competitions , And the progress of the carry system frequently appear, there are examinations of decimal, other systems, the conversion between the conversion system of the question, but also with the binary number symbolic
