every bounded infinite set of real numbers contains at least one point of accumulation(任何有界的实数无穷集至少包含一个聚点), a point in every open interval of which there is another point of the set. In other words, this property asserts the "completeness" (完备性)of the real numbers. ...
This text consists of many assertions, some big, some small, some almost insignificant. These assertions are obtained from the properties of the real numbers by logical reasoning. Assertions that are especially important are called theorems . An assertion's importance is gauged by many factors, ...
