数学证明以一定的形式表现,它由论题、论据、论证三个部分组成。数学证明的规则,也就是关于论题、论据与论证方式的规则。 一、关于论题的规则 关于论题的规则有以下两条: (1)论题必须清楚明确。 论题清楚明确,是证题的先决条件。论题不明确,含混不清,就无法进行论证。如果论题是虚假的,就不能去证明它是真实的。 下面三个命题都不确切。

Mathematical proof in a certain form of performance, which consists of thesis, argument, demonstration of three parts. Mathematical proof of the rules, that is, on the topics, arguments and arguments of the rules. First, the rules on the topic The rules of the topic has the following two rules: (1) The topic must be clear and definite. The topic is clear and definite, which is the precondition of the proof. The topic is not clear, ambiguous, you can not justify. If the thesis is false, you can not prove that it is real. The following three propositions are not exact.
