Actually, you CAN divide by zero.

Yes, it’s possible! You’ve probably heard that you “can’t“ divide by zero, but why not? As it turns out, adding in the inverse of a number is a well-defined process in math, similar to how you can add in the solution to x^2 = -1. The result is a new number system. In this video, we find out what happens when you apply this process to add division by zero. The result is a pleasant mix of surprising and completely expected. Notes: 1. Normal rules of algebra means a ring. 2. Topology is important too, but algebra alone is enough for 1/0. 3. Cup would be more correct symbol for union than plus, but this is YouTube :). 4. We did not need to start with the reals, adding 1/0 in any ring results in the zero ring. ― mCoding with James Murphy () Normal algebra rules: (mathematics)#Definition Localization: (commutative_algebra) Dyadic rationals: Made with Manim: SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos!
