Prove that 3.999... = 4
(In reply to
re: Ideas by Tristan)
I must agree with Tristan.... Gamer, your analogies don't apply.
What's more... you wrote:
"...I could say 3.999 [sic] doesn't really exist.
If you mean 3.999..., then generally, that is denoted with 3.9 with the 9 having a bar over it, indicating a repeating decimal. It exists simply because we write it in our nomenclature, and algebra has means to deal with such numbers.
