In mathematics, a '''variable''' is a number whose value is not known. In basic arithmetic problems, the variable is typically the answer which the student must find:
+
Two trucks having sex
 +
Two trucks having sex
 +
My muscles, my muscles
 +
Involuntarily flex
  
Given:
+
Two trucks having sex
5 + x = 12
+
Two trucks having sex
+
My muscles, my muscles
Find x.
+
Involuntarily flex
  
Since 5 + 7 = 12, the answer is:
+
TWO PICKUP TRUCKS
 +
MAKING LOVE
 +
AMERICAN MADE
 +
BUILT FORD TOUGH
 +
TWO BEAUTIFUL MURDER MACHINES
 +
AMERICAN ANGELS IN THE SKY
 +
GROWN MEN CRY
  
x = 7
+
Two trucks having sex (oh yes)
 +
Two trucks having sex (oh yes)
 +
My muscles (UH) My muscles (UH)
 +
Involuntarily flex
  
A variable is usually is the subject or part of a [[function]] and must be subject to change while not affecting the structure behind the function in which it acts.
+
Two trucks, having sex (oh yes)
 +
Two trucks, having sex (oh yes)
 +
my muscles (UH) my muscles (UH)
 +
Involuntarily flex
  
For example, if we have a function: <math>f(x,y)=x^{2}+3y</math>, then <math>x,y</math> are said to be the variables of the function, <math>f</math>.

 +
THIS BARBECUE COULD BRING YOU TO YOUR KNEES
 +
AND SO COULD THESE TWO TRUCKS
  
Further, <math>f(1,2)=(1)^{2}+3(2)=1+6=7</math>.  We change the variable and thus alter the value of the function.

Sometimes a function can have also a [[parameter]]. A parameter is similar to a variable, but is not written like a variable and is thus more similar to a [[constant]]. For example, if we a function: <math>f(x,y) = x^2 + ay</math>, then <math>a</math> is said to be a [[parameter]]. It does not change like the variables x and y, but it can nonetheless take different values. It is important to clearly distinguish the two concepts.

The [[set]] of all variables upon which a function acts is said to be the [[domain]].  The set of all values that a function can take due to its domain is called its [[range]].
