What is the term for an algebraic expression with exactly one term?

• A. Monomial
• B. Polynomial
• C. Rational Number
• D. Irrational Number

Answer: (A)

A single-term algebraic expression is called a monomial. A term is a piece that may be a constant, a variable, or a product of numbers and variables with nonnegative integer exponents, with no addition or subtraction inside. Examples include 5, -7x^2, and 4xy. A polynomial is just a sum of such terms; if there’s only one term, it’s still a polynomial, but the usual name for that one-term form is monomial. The other options describe numbers, not the structure of an algebraic expression, or describe a sum of terms rather than a single term.
