Did you know that The Simpsons is packed with mathematical references? From the writers' inside jokes to visual gags, the show has a rich history of sneaking in maths that even GCSE students can appreciate. In this post, we'll explore some of the most famous mathematical moments and show you how to tackle the underlying concepts step by step.
1. Fermat's Last Theorem in 'The Wizard of Evergreen Terrace'
In the episode 'The Wizard of Evergreen Terrace', Homer writes an equation on a chalkboard:
3987¹² + 4365¹² = 4472¹²
This looks like a counterexample to Fermat's Last Theorem, which states that no three positive integers a, b, and c satisfy aⁿ + bⁿ = cⁿ for any integer n > 2. But it's not! The equation is false—it's a near miss. The writers chose numbers that are very close to satisfying the equation, but not exactly.
GCSE Maths Link: This is a great hook for discussing powers and indices. For example, can you calculate 2³ + 3³? How does it compare to 5³? Use the order of operations (BIDMAS).
Step-by-step activity:
Calculate 2³ + 3³.
Calculate 5³.
Compare: Is 2³ + 3³ = 5³? Why not?

D --> E["Calculate 5³ = 125"]
E --> F["Is 35 = 125?"]
F -->|No| G["Fermat's Last Theorem holds!"]
2. Pi in 'Bye Bye Nerdie'
In the episode 'Bye Bye Nerdie', a character says: "Pi is exactly 3!" This is a joke, as pi is approximately 3.14159. But it's a great chance to revise circles.
GCSE Maths Link: Circumference and area of circles.
Step-by-step:
Recall: Circumference = π × diameter, Area = π × r².
Example: A circle has radius 5 cm. Find its area.
Area = π × 5² = 25π ≈ 78.5 cm² (to 1 d.p.).
pie title Circle Calculations
"Area" : 78.5
"Circumference" : 31.4
3. The Simpsons and Probability
In 'Homer the Smithers', Homer is asked to guess the number of marbles in a jar. He guesses 1,000, but the actual number is 1,234. This is a classic estimation problem.
GCSE Maths Link: Estimation and rounding.
Step-by-step:
Estimate the volume of the jar.
Estimate the volume of one marble.
Divide to get an approximate number.
Round to a sensible value.
4. The Maths of Donuts: Volume and Surface Area
Homer loves donuts. A donut (torus) has a fascinating shape. While GCSE doesn't require the volume of a torus, you can approximate it as a cylinder.
GCSE Maths Link: Volume of a cylinder.
Step-by-step:
A donut can be thought of as a cylinder with a hole.
Volume of cylinder = πr²h.
If the donut has radius 4 cm and height 2 cm, volume = π × 4² × 2 = 32π ≈ 100.5 cm³.

A["Donut"] --> B["Approximate as cylinder"]
B --> C["Volume = πr²h"]
C --> D["Substitute r=4, h=2"]
D --> E["Volume ≈ 100.5 cm³"]
5. The Simpsons and Statistics
In 'Much Apu About Nothing', Apu takes a citizenship test. The test has 20 questions, and Apu needs to get at least 15 correct. If he guesses randomly, what's the probability he passes?
GCSE Maths Link: Probability and the binomial distribution (higher tier).
Step-by-step:
Each question has 4 choices, so probability of correct guess = 1/4.
We need P(X ≥ 15) where X ~ B(20, 0.25).
Using a calculator or tables, this is very small (≈ 0.0000002). So Apu should study!
6. The Simpsons and Number Patterns
In 'Treehouse of Horror VI', there's a 3D world where numbers appear. One scene shows the equation 1782¹² + 1841¹² = 1922¹², another near miss for Fermat.
GCSE Maths Link: Number patterns and sequences.
Step-by-step:
Look at the pattern: aⁿ + bⁿ ≈ cⁿ.
Can you find other near misses? Try n=3, a=6, b=8, c=9: 6³+8³=216+512=728, 9³=729. Close!
7. The Simpsons and Geometry
In 'The Computer Wore Menace Shoes', Homer becomes a web detective. He uses a map with coordinates. This is a chance to revise coordinates and transformations.
GCSE Maths Link: Coordinates and transformations.
Step-by-step:
Plot points on a Cartesian plane.
