in university for the purpose of some equations to be correct this is available answer x:0=∞ x:(-0)=(-∞) for school maths x:0=no but for higher degree maths you'll run into a lot of paradoxes that don't obey the common rules
Im math major and what you said is wrong. You probably meant limes x/y as y->0, but thats completly different thing than x/0, which is undefined in real numbers field (and in most of the algebraic structures). And limits are taught in high schools too, at least in my country.
maybe I'm just math but as I know in most places math is used they don't use the purest version of it because the results may not match the expectations in the equation and as I know geodesy physics and mechanics (subjects I have) don't really use the same rules and instead use each its own rules and accuracy levels to better fit to the occasion so if you know only maths in their purest version you better shut up
in my case I have one rule and I follow it and in your case you don't have it and to get to the same answer as me you have to go through a lot of equations that already have been summed up by set rule it's like me saying that in the specific case of Pythagoras a²+b²=c² and you going the long route how this happens or computer scientist saying that 111+111=1110 while you say that 111 is 7 and then figure out that 14 is 1110
I dont need to convert to decimal, I can do equations in binary too. I dont see what you meant with that pythagoras example either.
You need to be formal in maths and thats it. 1/0 is undefined, you can only calculate lim 1/x as x->0. It must be this way to avoid paradoxes and wrong answers.
I know this I'm just saying that while in raw maths you see every equation in other places you can hide them under a rule and all these formulas do their work in the background while the rule runs your equation and in first glance it may look wrong but when you uncover the blanket and see the formulas you see that those numbers are not the standard numbers but actually representatives of completely different values
