關(guān)于新版gre數(shù)學(xué)復(fù)習(xí)重要考點(diǎn)
俗話說：工欲善其事必先利其器。很多參加了新版gre考試的同學(xué)都覺得數(shù)學(xué)有點(diǎn)難度，相信這其中的原因還是由于考生在新版gre數(shù)學(xué)復(fù)習(xí)時(shí)沒有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點(diǎn)都沒有復(fù)習(xí)到，如何能拿到分?jǐn)?shù)呢?所以說，想要新版gre數(shù)學(xué)考好，復(fù)習(xí)的時(shí)候一定要把基本概念和重要考點(diǎn)都弄扎實(shí)。
今天針對(duì)新版gre數(shù)學(xué)復(fù)習(xí)，小編給大家整理的.是關(guān)于Combinations of Choices的相關(guān)內(nèi)容，這些概念在考試中一定會(huì)考到的。希望考生能再接再厲，取得一個(gè)好成績(jī)，突破新版gre數(shù)學(xué)難的困境。
新版gre數(shù)學(xué)復(fù)習(xí)重要考點(diǎn)：Combinations of Choices
If there are n choices for one type and m choices for second type, then number of combinations for both types is the product of choices:nm.
Example:
If there are 3 kinds of breads to choose from and 4 kinds of meats, then we can make 34=12 different sandwiches.
If an alphabet has 26 letters, then the number of possible 2 letter word is 2626=676.All of them may not be vaild words.
Remember:
Do not add the choices to get the total combinations.
