Algebraic Expression
One or many terms connected by algebraic operations is called an algebraic expression. The operations between the terms must be valid to yield an expression.
Example
(3x+5),(ax2+c),and (xy+a)(x+y) are all algebraic expressions.
(2x+5)+·(3x) is not an expression since + followed by· is not a valid sequence of operations.
Remember
There is no=sign in an expression.
有一部分考生認(rèn)為新GRE數(shù)學(xué)具有一定的難度，這其中的原因是由于考生在復(fù)習(xí)時(shí)沒(méi)有把新GRE數(shù)學(xué)的基礎(chǔ)打牢。想要新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)。
