An algebraic expression
is a valid combination of , , and mathematical operations.
For example, in the expression 2x+3,
the variable x
is being multiplied
then, this product is added
to the 3.
Algebraic expressions come in many forms; they can be , like the 2x
in the above expression. In a , each monomial separated by a
sign is called a .
An entire polynomial, like the above , is also called an algebraic expression. However, an expression that only contains constants is called a
