新GRE数学要点:Algebraic Expression
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.
