Human 1
Why can’t we divide by zero?
AI 2
Dividing 12 by 3 asks which number multiplied by 3 gives 12. No number multiplied by zero gives 12.
Human 3
But zero divided by zero is different, isn’t it?
AI 4
Yes. Every number multiplied by zero gives zero, so there is no single answer. That is why 0 ÷ 0 is undefined in ordinary arithmetic.
Human 5
Then why do I see 0/0 when people talk about limits?
