  2014年,又有哪些GMAT數學題型獲得了GMAT考試出題人的青睞?對于早已開始武裝自己的考生來說,情報現(xiàn)在對于他們來說,無異于考試生命。為了讓考生及時掌握2013年GMAT數學將要考查的基本概念,指導考生的GMAT數學復習,本文特別進行了大搜索,功夫不負有心人,這就為您呈現(xiàn)。

  分數:fractions

  分子:numerator

  分母:denominator

  分數的加減乘除:addition,subtraction,multiplication and division of fractions

  繁分數和假分數:mixed number and improper fraction

  繁分數是指一個數由一個整數和一個分數構成。

  假分數是指分子大于分母的分數。例如:7/3

  小數:decimals

  科學計數法:scientific notation

  Sometimes decimals are expressed as the product of a number with only one digit to the lt of the decimal point and a power of 10. This is called scientific notation. For example, 231 can be written as 2.31×102 and 0.0231 can be written as 2.31×10-2. When a number is expressed in scientific notation, the exponent of the 10 indicates the number of places that the decimal point is to be moved in the number that is to be multiplied by a power of 10 in order to obtain the product. The decimal point is moved to the right if the exponent is positive and to the lt if the exponent is negative. For example, 20.13×103 is equal to 20,130 and 1.91×10-4 is equal to 0.000191.

  看完本文關于2013年數學復習基本概念的介紹,考生是否心里有個譜了?建議考生根據2014年GMAT數學重點概念的調整,調整自己的GMAT數學復習計劃,合理調配GMAT數學復習時間,此外,考生仍然要對GMAT數學基本概念進行研究,這是GMAT考試的根系所在。
