Not only is The Simpsons the most
watched animated television show
among 18-49 year olds1, but it is also
the most mathematically sophisticated
as well.
Executive Producer Al Jean studied
mathematics ta Harvard at age 16;
Senior research post Jeff Westbrook
left Yale University to be a
scriptwriter on The Simpsons, and the
writer himself, David X. Cohen, who
has a degree in both physics and
computer science2 from Harvard and
UC Berkley respectively.
There are dozens of examples of
mathematical references planted into
episodes of The Simpsons, only some
of which are illustrated in this booklet.
Connecting curriculum requirements to
episodes of The Simpsons will not only
get the attention of your students, but
with effective delivery, will enhance
their understanding of the subject
matter as well.

After Homer’s heart attack, Homer is convinced that Lisa just gave away $12,000. Lisa corrects him “Um, Dad, ten percent of $120,000,000 isn't $12,000. It's.…”
What is 10% of $120 000 000? What is this number expressed as a fraction? Show all work.

SPECIFIC EXPECTATIONS
Probability - By the end
of Grade 7, students

S08E21: The Old Man and the Lisa
Grade 7: Data Management & Probability
In the United States, your odds of winning the lottery depend on where you play. Single state lotteries have odds of approximately 18 million to 1, while multiple state lotteries can have odds as high as 120 million to 1. The National Safety Council states that the odds of getting hit by lightning is on average 100 people/year. If the US population is 314 million people, then what percentage of people are struck by lightning per year?
Do you have a better chance of winning the lottery or getting struck by lightning? How much of a better chance do you have? Explain your answer.
Solutions for Lottery Odds:
1
18 million = 0.0000000556 x 100% =
0.00000556%
1
120 million = 0.00000000833 x 100%
= 0.000000833%
Solutions for Lightning Strikes:
100 people/year
314,000,00 people = 0.000000318 x
100%
=0.0000318% of people in the US get
struck by lightning each year.
0.000000318
0.00000000833= 38
Thus, you have a higher chance of
getting struck by lightning than
winning the lottery by 38 times.

PYTHAGOREAN THEORM
Explain Pythagorean Theorem to be: c2 = a2 + b2 or
and: 𝒄𝟐 = 𝒂𝟐 + 𝒃𝟐 “The sum of the squares of the two shortest sides of a right triangle is equal to the square of the hypotenuse”. Define term hypotenuse
Grade 8: Geometry & Spatial Sense
Play this clip for your class, then pause it at 00:06. Homer states that “the sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side”. Have your students test this with the isosceles triangles above. What conclusion do they come to?
3 cm 3 cm
5 cm 2 cm
3 cm 3 cm
Now try a right angle triangle. Have them watch what happens when you put a square on each side. What’s the area of the biggest
square?
What’s the area of the two smaller squares put together?
Have students come up with a rule to explain this (Pythagorean Theorem)
3 cm
4 cm 5 cm
PYTHAGOREAN THEOREM
Replay the clip above fully, and ask the class what was wrong in Homer’s statement that the man in the stall
didn’t catch?
Solution: Homer’s statement, ‘the sum of the
square roots’ implies: 𝑎 + 𝑏 = 𝑐; and:
Homer implies that the sum of the square roots of any 2 sides will give you the square root of the 3rd side, but it only works for the
2 shortest sides

S25E10: Married to the Blob
At 01:39, Radioactive Man appears defeated and starts losing his life
force. The radioactive symbol on his chest shows how his power
declines. Answer the following questions:
1. Does Radioactive Man’s power decline linearly? If not, how does his
power decline?
2. Graph your results and find what equation models his power decline.
3. Hypothetically, if the radioactive symbol had 6 bars instead of 3, in
what stages would his power decline? Would this have helped him
survive? Solutions:
1. His power declines exponentially in powers of 2. 1 to ½ to ¼ to 1/8.

Solution: Since the bases are the same (3), set their exponents equal: 2-x = 1, x = 1.
5) 42x+1 = (0.5)3x+5
Solution: First write both sides with the same base (2). (22)2x+1=(2-2)3x+5, then use power of a power rule: 24x+2 = 2-6x-10, set exponents equal: 4x+2=6x-10; 12=2x; x=6. 6) 2x-1 + 2x + 2x+1 = 7
Solution: Use graphing technology, and graph y = 2x-1 + 2x + 2x+1. Find the x-value where y=7 (x=2)
Fermat’s Last Theorem
Fermat looked at solutions to the Diophantine Equation, ax + bx = cx, for x>2 and a,b,c ≠ 0,
and discovered something quite peculiar – this equation has no solutions for x being an integer. Notice that x=2 returns the Pythagorean Theorem.
In this episode of Homer3, pause the video at approximately 03:20, and have students reflect on the equation in the background. Has Homer stumbled into a 3D universe where Fermat’s Last Theorem is incorrect? Why or why not? How can you tell by just looking at the equation(see solutions at end of booklet)?

INTRODUCTION TO 3-SPACE, R3
Recall Vectors in 2D Space:
|c| = |𝑎|2 + |𝑏|2
Any point P(x,y) in R2 can be thought of as a vector c, whose magnitude is
|c| = |𝒙|𝟐 + |𝒚|𝟐
The direction of P(a,b) can be found using the tangent of the component vectors:
c is θo above the horizontal, where tanθ = b/a, θ = tan-1(b/a)

b c

1) Explain why when falling
through the wormhole, it is not
sufficient to describe Homer’s
position in R2?
Solution: Because there is depth
to his location now as well. You
would measure z from the same
reference level as x and y.
2) Based on how we found the
magnitude for a vector in R2,
predict the formula for the
magnitude of a vector in R3.
Solution: |c| = |𝒙|𝟐 + |𝒚|𝟐 + |𝒛|𝟐
3) How does the position of Homer’s
feet in R3 compare to that of his
head?

Feel free to assign your own coordinates.
4) Predict approximately how you
would determine his exact position
in R3.

TRYING SOME EXAMPLES
1) 6x5*3x-2 = ?
Left Side: Multiplying exponentials, therefore add exponents of x and multiply coefficients 6
and 3. LS: 18x3
2) 5x-4*2x-3 = ?
Left Side: Multiply coefficients 5 and 2 together to get 10, and add exponents of x, (-4)+(-3)
= -7. LS: 10x-7
3) 6x5/3x-2 = ?
Left Side: Divide the coefficients, 6 by 3 = 2, and subtract the exponent of the denominator
from the exponent in the numerator, (5)-(-2) = 5 + 2 = 7, thus you end up with: 2x7
FERMAT’S LAST THEOREM – DISPROVEN?
At 03:20 in the clip, there is an equation in the background:
178212 + 184112 = 192212, which seems to be in opposition to Fermat’s Last Theorem,
which states that an equation in the form ax + bx = cx, for x>2 and a,b,c ≠ 0, cannot exist
when x is an integer.
In this case, x=12 is an integer – plugging it into our calculator gives us:
LS: 2.541210259 x 1039 and RS: 2.541210259 x 1039
At first glance, it seems like the laws of this 3D universe have altered and disproven
Fermat’s Last Theorem. However, upon closer inspection, one sees that it still holds true.
Notice that you’re calculator only goes up to 9 decimal places. If we plug the same
numbers into a device/software that generates more decimal places, we would have found
