why is it that we can literally invent and conjure up a definition for square root of a negative number (something that eluded us for a millennia) but cannot define division by zero? Imagine how many problems in both math and physics could be solved if we could find a definition to division by zero.

not a math boy but doesnt ring theory or some shit allow for division by zero

going with the example you gave:
No matter how many imaginary/additional dimensions you add, their common intersction will always be at 0. Of course you could simply define something else. You could then use your definition to make division by zero possible. The problem is that it wouldn't be currently useful in any way, like imaginary and komplex numbers by extension are.

some number systems include division by zero. It can all be defined. Like Wildberger defined a number system with formal infinitesimals

division by zero allows things like 1=2 and other really wacky shit

it's not possible and we don't need it

Ok I just defined it I made a magical number called "d0" which is the result when you divide a number by zero. If you think that's a copout go plot 1/x on a graphing calculator and tell me what you think my magical number should be.

You can also define the answer to any division by 0 to be ±∞ but it's not like that's very useful either. Anyway, I'm expecting some answers to those math and physics questions you alluded to that are now solved by my magic number thank you.

do we need it? and if so, what for? otherwise it'll just be definitions upon definitions.

You don't just "define" stuff out of mid air. You have to demonstrate that the defined object itself stands "on its own" AND that you can find examples of said object.

Its not undefined its just that nothing happens. If i divide my cake into 0 pieces i just dont cut it and it remains 1 piece.


There i solved it for ylu, egghead now back to the amazon warehouse

it's not that we can't, it's that we choose not to. It's a convention adopted by consensus of math scholars. Mostly because nobody has proposed any meaningful interpretation of what it would mean to do otherwise.

That was worded pretty awkwardly like you were purposely trying to cause confusion, you should have just said if you divide your cake 0 times.

Division by zero is unironically more natural than a "square root of a negative number".

This is how smooth the brain of a "complex number" ideologist looks like. Not just smooth, even holomorphic.

LMAO, this guy got filtered out by complex numbers. His brain will go poof once he sees hyperbolic numbers.
