摘要： GRE数学中除了各类知识点和考点外，题目本身也具备一定的出题原则和规则，而许多默认的条件则并未直接写明。不过考生需要对这些出题原则有所了解，如此才能更有效率的解题。下面就由小编为大家介绍ETS官方公布的GRE数学出题原则。 gre免费课程 ETS官方关于GRE数学考试出题原则的介绍 ●All numbers used are real numbers; ●All figures lie on a plan
●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.
