Others pointed out that 2.3 rounds down to 2, but 2.3+2.3 rounds up to 5, making it possible through a certain filter that 2+2=5. Many people pointed out that two animals can become three through reproduction (1+1=3, or 1+1=1, depending on your parameters), or that two machines could become three machines if you had some spare parts from each machine and a little elbow grease.

But a 360-degree angle has the same orientation as a 0-degree angle, so whether the angle measures 0 degrees or 360 degrees depends on context. Arithmetic works well in a textbook, but practically, it often runs into contextual questions that don’t account for parts of a whole, approximations, or more relevant vectors.įor example, if you’re adding whole degrees to an angle, eventually you’ll circle around to an angle that measures 360 degrees.

In his Twitter thread, Carr pointed out that counting numbers “are abstractions of real underlying things in the universe,” so we should be mindful of how those abstractions distort truth when introduced to real-world scenarios.

On July 30, he wrote, “I don’t know who needs to hear this, but if someone says 2+2=5, the correct response is, ‘What are your definitions and axioms?’ not a rant about the decline of Western civilization.” student at Harvard University, ignited a “Does 2+2 ever equal 5?” debate on Twitter. “I don’t know who needs to hear this, but if someone says 2+2=5, the correct response is, ‘What are your definitions and axioms?’ not a rant about the decline of Western civilization.”
