Factor
Any integer
or polynomial that exactly divides a given integer or polynomial.
Factor a polynomial means decompose it in simple (prime) factors.
Thus 2, 3, 4, 6, 12 are factors of 12, but the prime decomposition
of 12 is  .
For example factoring the polynomial:  .

Formation
Rules
In logic, the
rules of a formal language constructing well formed formulas (WFF)
from symbols. For example, 
are WFF, but 
are not.

A formal expression
of some rule .
Fraction
Any ratio of
one quantity to another non-zero quantity.
Function
A function is
a rule that assigns to every element x of a set X, a
unique element y of a set Y, written as y = f(x). X
is called the domain and Y the codomain and the set of all elements
f(x) is called the range or image of f. The
range is a subset of the codomain, but in all basic level
of mathematics are seen as equals.
To help understand this definition, we look at the function as an
input-out machine where the set of all allowed inputs is the domain
and the set of all outputs obtained is the range.
