GRE數學考試在新GRE考試當中增加了一些難度,但是考生也不要太緊張,只要把一些GRE數學基本概念掌握好,解題時就一定能輕松應對。
數學各個數位的表達
個位:units,ones
個位以上的其他整數數位:基數詞+S
例如:十位 tens
小數位:序數詞+S
例如:十分位 tenths
例題:A worker numbered the pages of a book, with 1 on the first page. In numbering the page, he printed a total of 63 digits.
A. the number of pages in the book

四舍五入(至十分位)
分數 fractions

A.10%
B.20%
C.30%
D.50%
E.60%
數列sequence/progression
等差數列:arithmetic sequence
等比數列:geometric sequence
等差數列前N項求和:
(首項+末項)x項數/2
有窮數列:finite sequence
無窮數列:infinite sequence
平時,建議大家一定要注意GRE數學基本概念的加強理解,因為無論GRE數學考試怎樣的題目都是從最基本的概念中演變而來的。
