If x - x = 0 then why can't we divide by 0?

Are you some sort of retard? You can divide by zero. You just don't because you're a coward. Find some sensibility in your fear of quantum dynamics but you will never be at peace.

Good shit sci. Noone even noticed that e^(ipi) is in fact equal to negative 1. Jesus christ.

Beat me to it. e^(i * pi) = -1 , or e^(i * tau) = 1 if you don't like negative numbers.

Prove why you can divide by zero, and I'll give you a million dollar, field medal, and a tenure track position at a top 10 global university. By the way those are the prizes for dividing by zero. Its a real thing.

Lul

You do know that not dividing by zero is just a convention because it makes things behave nicely, right?

>>7693404
e^(pi*i) is -1 dumbass

Can we...
e^(pi*i)=x
lnx=pi*i
lnx^(2)=pi^(2)*i^(2)
lnx^(2)=pi^(2)*-1
lnx^(2)^(2)=pi^(2)^(2)*-1^(2)
lnx^(4)=pi^(4)*1
lnx^(4)=pi^(4)
lnx=pi
Can we do that?

It can be proven that the additive identity in any field does not have a multiplicative inverse.
