A stick figure teacher stands in a classroom next to an old TV set and a chalkboard that reads "Adjective: a white shirt, a handsome tie."

He says NOW THAT WE'RE DONE WITH
OUR ENGLISH LESSON
FOR THE DAY AND DESCRIBING
WHAT A GREAT TEACHER
AND HOW HANDSOME I AM, IT'S
TIME TO MOVE ON TO MATH.
YES, IT'S TIME FOR
ANOTHER VIDEO.

[class cheering]

The teacher says THIS ONE IS A VARIATION
ON WHAT WE NORMALLY WATCH.
IT'S ON VARIABLES.
WHAT'S A VARIABLE?
WELL, A VARIABLE IS A PART
OF A PROBLEM YOU HAVE
TO FIGURE OUT.
LIKE THE PROBLEM OF HOW
TO GET THE TV WORKING.
HA, HA, HA.

[crickets chirping]

The teacher says AHEM.
I'LL FIGURE IT OUT.
HERE WE GO.
UH... PRESS PLAY.

He turns on the old TV.

(music plays)

As the expression "x + 7 = 12" appears, a song says
A VARIABLE IS A SYMBOL FOR A
NUMBER THAT WE DON'T YET KNOW
WE CAN FIGURE OUT
THIS NUMBER
COME ON, LET'S GO
TO FIGURE OUT A VARIABLE
WHEN DOING AN EQUATION
JUST ISOLATE THE VARIABLE
AND DO THE
OPPOSITE OPERATION...

The numbers and symbols shift, forming a new expression that reads "X = 12 – 7"

The song continues
LET'S SEE...

A male voice says
OKAY, HERE'S THE PROBLEM:

The expression goes back to its original form of "X + 7 = 12"

The male voice continues ISOLATE THE VARIABLE
ALL BY ITSELF.
AND WHAT YOU DO TO ONE SIDE,
YOU GOTTA DO TO THE OTHER.

The expression changes to "X+7-7=12-7"

The male voice says
7-7=0
AND THEY CANCEL
EACH OTHER OUT.
And X=12-7.
SO... X = 5
NOW FINISH THE EQUATION
5+7=12.

[cheering]

The song says
A VARIABLE IS A SYMBOL FOR A
NUMBER THAT WE DON'T YET KNOW
WE CAN FIGURE OUT
THIS NUMBER
COME ON, LET'S GO
TO FIGURE OUT A VARIABLE
WHEN DOING AN EQUATION
JUST ISOLATE THE VARIABLE
AND DO THE
OPPOSITE OPERATION...

[cheering]

The song ends and the stick figure teacher turns off the old TV.

He says
SO NOW YOU KNOW VARIABLES.
LET'S PRACTISE.
WHAT'S A PROBLEM WITH A
VARIABLE WE COULD SOLVE?
UH, HOW MANY VIDEOS
I WATCH IN CLASS?
WELL, I GUESS WE'D HAVE TO
TAKE THE AMOUNT OF CLASSES
AND DO THE OPPOSITE
OPERATION.
LIKE STOP WATCHING VIDEOS.

[class booing]

The teacher says
YOU DON'T LIKE THAT ONE?
WELL, WHAT'S
ANOTHER ONE?
HOW LONG UNTIL LUNCH?

[bell ringing]
[cheering]
[whistling]
