A monomial is an expression in algebra that contains one term,
like 3xy. Monomials include: numbers, whole numbers and
variables that are multiplied together, and variables that are
multiplied together. Any number, all by itself, is a monomial,
like 5 or 2700. A monomial can also be a variable, like “m” or
“b”. It can also be a combination of these, like 98b or 78xyz.
It cannot have a fractional or negative exponent. These are not
monomials: 45x+3, 10 - 2a, or 67a - 19b + c. Two rules about
monomials are: When looking at examples of monomials, you need
to understand different kinds of polynomials. Following is an
explanation of polynomials, binomials, trinomials, and degrees
of a polynomial. A polynomial is an algebraic expression with a
finite number of terms. These terms are in the form “axn” where
“a” is a real number, “x” means to multiply, and “n” is a non-
negative integer. Examples are 7a2 + 18a - 2, 4m2, 2x5 + 17x3 -
9x + 93, 5a-12, and 1273. A binomial is a polynomial with two
terms. 3x + 1, 2x3 - 5x,
