This. 1/0 does not exist in our number system. Alternate number systems allow 1/0 to exist at the expense of many useful properties of mathematics that (OC?) OP doesn’t seem to understand. Not everything in math has to make sense: we simply gave ourselves some set rules, and then built up a system off the consequences of those rules. If 1/0 cannot exist within those rules, then that’s it. If you’re going to argue against centuries of mathematical advancements then so be it, I can’t stop you, but it’s pretty obviously a losing battle.
