15. Why didn’t the two 4’s want any dinner?

Answer: Because they already 8! This question plays with the sound similarity between “eight” and “ate,” turning a simple addition into a story about numbers not needing dinner.

16. What do you get when you cross geometry with McDonald’s?

Answer: A plane cheeseburger. This clever pun combines “plane” from geometry, referring to a flat surface, with a plain cheeseburger from McDonald’s, suggesting a humorously geometric meal.

17. How do you stay warm in any room?

Answer: Go to the corner; it’s always 90 degrees. Mixing a common physical perception with geometric fact, this joke points out the warmth of corners in degrees, rather than temperature.

18. Why is algebra so easy for ghosts?

Answer: Because they’re great with “spirit”ed numbers. This pun plays on the word “spirited,” referring to ghosts’ nature, and suggests they excel in algebra, where working with abstract numbers is common.

19. What did the mathematician say to the sun?

Answer: “You can count on me to follow your tangents.” This pun refers to both a mathematician’s ability to understand complex concepts like tangents in trigonometry and the idea of faithfully following or being interested in someone’s less relevant narratives.

20. What’s a bird’s favorite mathematical operation?

Answer: Owl-gebra. Combining “owl,” a type of bird, with “algebra,” this pun creates a whimsical image of birds engaging in mathematical operations, suggesting their preference for algebra with a playful twist on the word.
