小伙伴们，GRE考试大家复习的怎么样了呢？下面是帮考网分享的一些GRE考试数学部分的复习资料，一起来看看吧！

一、在新GRE数学考试中，一般都假定以下信息为真：

All numbers used are real numbers;

All figures lie on a plane unless otherwise indicated;

All angle measures are positive;

All lines shown as straight are straight. On the computer-based test， lines that appear“jagged" can also be assumed to be straight (lines can look somewhat jagged on the computer screen)：

Figures are intended to provide useful information for answering the questions. However，except where a figure is accompanied by a“Note" stating that the figure is drawn tO scale， solve the problem using your knowledge of mathematics， not by visual measurement or estimation.

细心的考生会发现，上述假设实际上就是ETS 出题原则，即：

所有的数都是实数;

除非题目中专门指出假设所有图形都在同一个平面内;

所有的角的测量值都是正数;

所有显示为直线的线均可当作直线来处理(在机试中，因为电脑显示器的原因，直线可能会看起来呈“锯齿状”);

伴随问题的图形将为解题提供有用的信息。但是，只有在问题中指出本图形是按比例画出(drawn to scale)时，才可以用目测或估计而得到的信息去解题。否则，只能运用你的数学知识去回答问题。这一解题原则可以简称为“只能读图，不能度量”的原则。

二、算术也是GRE数学考试的重头戏之一，要复习算术类GRE数学题，不妨从下面的的典型例题开始。
