- The Nimbus ship has the serial number "BP-1729", a reference to the Hardy-Ramanujan number, the smallest non-trivial taxicab number.
- Flexo's and Bender's serial numbers, 3370318 and 2716057 respectively, are a sum of two cubes(this not really a reference):
- 3370318 = 1193 + 1193
- 2716057 = 9523 + (-951)3
- While Fry and Amy are in the closet, there are two books labelled P and NP. This refers to the P versus NP problem in computer science.
- Outside of Bender's computer dating service, the sign advertises that it is "discreet and discrete", referencing the field of discrete mathematics.
- This episode as well as in "I Dated a Robot", features the theater Loew's ℵ0-Plex. ℵ (aleph) is used in a sequence of numbers to represent the size of infinite sets. Also, the suffix -plex means how many screens in a cinema. In this case, the ℵ would indicate that there is a countably infinite number of screens in Loew's theater. (it represents the cardinality, not the size).
- On the billboard that Leela again crashes, it shows how much Popplers were sold. It says: 3.8 x 1010 popplers sold. That number is the average distance from the Earth to the Moon (measured in centimetres).
- Bender sees the number 1010011010 in the mirror. After the binary digits have been decoded, it reads "666".
- In this episode, a sign reads Historic √66 (pronounced Historic Root 66, or Route) is a parody of the U.S. Route 66. It is also an irrational root.
- The π-in-1 oil is an oil lubricant, with an irrational amount of oils in one.
- πth Avenue is an irrational avenue, one of the many irrational references by the Futurama writers!
- πkea is yet another irrational number reference.
- In Bender's Big Score, Al Gore drives a cab that has the number 87,539,319 on it. This is the third taxicab number.
- Sweet Clyde demonstrates some razzle-dazzle Globetrotter calculus using variation of parameters and expanding the Wronskian, both techniques used to solve differential equations.
- In The Beast with a Billion Backs, Colleen can be seen wearing a shirt with a quantified statement at the church where Yivo is introduced. The statement reads "For all X, I Love (heart) X."
- In the beginning of Bender's Game, the Planet Express ship goes through various numbers, that are the digits of e. The number e, as π, is irrational and has infinite digits.
- The ⁴√4 in Channel ⁴√4 is an irrational number, equal to √2.
- Prof. Farnsworth invents a copy machine that makes 2 exact duplicates of any object. The model on the copier (that looks like an old overhead projector) says Banach-Tarski. From Wikipedia The Banach–Tarski paradox is a theorem in set-theoretic geometry, which states the following: Given a solid ball in 3‑dimensional space, there exists a decomposition of the ball into a finite number of disjoint subsets, which can then be put back together in a different way to yield two identical copies of the original ball."
- While talking of irrational numbers, the √2 in Channel √2 News an irrational number itself, which means (possibly) that there are root signs on remote controls, and more irrational channels out there.
- 7¹¹, equal to 1,977,326,743, is a convenience store open 28 hours a day (possibly 7:00 AM until 11:00 AM of the following day. Or, time has been recalibrated in the future).
- There is a game show asking "What's the last digit of π?", and the man answers 7. But π is an irrational number, which means it doesn't end. He would be right if the statement "If there is a last digit of π, then it is 7" were true, and wrong if the statement "There is a last digit of π, and it is not 7" were true. In logic, the statement "if p then q" is vacuously true if p is false.
