no one knows what is the last number of pi

markisabeast · Answer

thankyou finally a helpful response

nincompoop · Answer

you were helped with your first question 
pi has no unit because it is not of a measurement

tkhunny · Answer

I'm going to argue with nincompoop.  There isn't a last digit.  That's a little different from just not knowing it.

nincompoop · Answer

I don't think you're saying anything that disagrees with what I said 
it has an infinite place value, so no one knows the last digit of pi (there isn't one)

true dat

tkhunny · Answer

"Doesn't exist" is strong than "no one knows".
"No one knows because it doesn't exist" is a bit disingenuous or misleading.

In the teaching of mathematics, we need to be very clear about existence.  So many young students are confused on this point.  "There really is no such thing." is very different from "So far, no one is clever enough to find it."
