In these cards are some definitions and the statement of a few simple rules.


Monomial: is an algebraic expression consisting of a coefficient (real number) and a literal part in which they appear only multiplication and integer power.
The monomial can be a function in which all letters are variable (meaning that each letter can replace a real number).

Examples monomial
Coefficient monomial
Literal Part monomial

A monomial without literal part is called constant (4 is a constant ); 0 is the null monomial.
It is said that a monomial is in normal form if it is expressed with a single coefficient that multiplies the letters (written in alphabetical order) each of which appears only once with a given exponent. All proposed above are monomials in normal form, while the next is not:
