GRE數學要點
一、數學考察的范圍
1.Arithmetic算術部分包括整數的性質和種類，比如整除性、因子分解、質數、余數、奇數偶數；算術運算、指數、根；估算、百分比、比、比率、絕對值、數軸、小數表達、數列。
2.Algebra代數包括指數運算；因式分解、簡化代數式；函數、等式、不等式；解一次方程和二次方程、解不等式；解聯立方程、方程組；用方程解決文字題；解析幾何、函數圖像、函數圖像解方程和不等式、截距、斜率。
3.Geometry幾何包括平行、垂直、圓、三角形、等腰三角形、等邊三角形、306090三角形、四邊形、其他多邊形、全等和相似圖形、三維圖形、面積、周長、體積、畢達哥拉斯定理、角度計算。不考察證明的能力。
4.Data analysis包括描述統計學比如平均數、中位數、眾數、極差、均方差、四分位差、四分位、百分位；分析圖和表，包括折線圖、柱狀圖、餅圖、箱型圖、散點圖、頻數分布；概率初步、合成事件、獨立事件、隨機變量、概率分布、正態分布；計數方法、排列、組合、維恩圖。不考推論統計。
二、數學考察的題型
四種題型：
1.數值比較quantitative comparison questions
2.單選題 multiple-choice questions----select one answer choice
3.多選題 multiple-choice questions----select one or more answer choices
4.數值輸入題 numeric entry questions
三、答題的注意事項
1.become familiar with the answer choices.
2.avoid unnecessary computations.
3.remember that geometric figures are not necessarily drawn to scale.
4.plug in numbers
5.simplify the comparison
6.use the fact that the answer is there.
7.examine the answer choices
8.for questions that require approximations, scan the answer choices to see how close an approximation is needed.
9.note whether you are asked to indicate a specific number of answer choice or all choices that apply.
10.in some questions that involve conditions that limit the possible values of numerical answer choices, it may be efficient to determine the least and/or the greatest possible value.
11.avoid lengthy calculations by recognizing and continuing numerical patterns.
12.make sure you answer the question that is asked.
13.if you are asked to round your answer, make sure you round to the required degree of accuracy.
14.examine your answer to see if it is reasonable with respect to the information given.
15.填空題幾個注意：1要先點選輸入框 2刪除要用backspace 3負號就用那個連詞符號 4如果要改成正的，再次輸入連詞符號就變成正數了 5計算器上的transfer display可以直接把計算器里得出的結果轉到輸入框里面 6 2.5和2.50是一樣的 7 除非要求四舍五入，否則不要輸入近似值 8如果是分數，一般分子和分母是兩個獨立的框 9分數不必須約分
16.scan the data presentation briefly to see what it is about, but do not spend time studying all of the information in detail
17.bar graphs and circle graphs, as well as other graphical displays of data, are drawn to scale, so you can read or estimate data visually from such graphs.
18.the questions are to be answered only on the basis of the data presented, everyday facts , and your knowledge of mathematics.
19.MR表示 memory recall, M+ 表示memory sum, MC 表示 memory clear.
20.當第一次按M＋，屏幕上顯示的數字被紀錄在計算器的內存里面，屏幕右邊出現M字母，表示內存記憶被使用。以后每一次按M＋按鍵，都會把當前的屏幕上顯示的數字加到內存的數字上，并以得到的和來取代原來內存的記憶值。當按MR按鍵的時候，內存里面記憶的值被調出，就是最后的結果。如果要清空內存，按MC按鍵，這個時候右邊的M標志就消失了
