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.
