会计考友

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
