introductory algebra:
In intermediate algebra and in other branches of arithmetic, letters are used to represent numbers with unknown or unassigned values.
A number represented by a letter is called a literal number, and any number expression in which one or more number symbols are letter is called a literal expression.
In any number expression the parts connected by the signs + or - are called terms. An expression by either of the signs + or – consists of one terms, and is called a monomial. An expression consisting of two terms is a trinomial. In general, an expression consisting of three or more terms is called a polynomial in intermediate algebra.
