2012年新GRE数学考点指导——Algebraic Expression(1)

2012-11-03 

  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.
