Dear PF Forum,
I just read Math FAQ
These rules are not int practice. Is this true?
Because 30 years ago in high school, I was taught.
x/zero is infinity, error in computer.
zero/zero is undefined, not zero. Also error in computer.
So zero/zero is undefined or zero?
Thanks for anyhelp confirming my doubt.
[Add: is not in practice today, implying that in the old days some calculation still use zero/zero = zero.
When was it's not in practice?]

Please confirm.micromass said:The goal of this FAQ is to clear up the concept of 0 and specifically the operations that are allowed with 0.[..]Our concept of "zero" as a both a placeholder and a number originated in India in the 9th century. But mathematicians were quite unsure about how to work with zero. For example, some rules involving zero were
As we shall soon see, these rules are not in practice today.
- A number when divided by 0 is a fraction with 0 in the denominator.
- Zero divided by zero is zero.
