Nevertheless, the matter of overly simplified illustrations of the equality is a subject of pedagogical discussion and critique. Byers (2007, p.39) discusses the argument that, in elementary school, one is taught that 1⁄ 3=0.333..., so, ignoring all essential subtleties, "multiplying" this identity by 3 gives 1=0.999.... He further says that this argument is unconvincing, because of an unresolved ambiguity over the meaning of the equals sign; a student might think, "It surely does not mean that the number 1 is identical to that which is meant by the notation 0.999...." Most undergraduate mathematics majors encountered by Byers feel that while 0.999... is "very close" to 1 on the strength of this argument, with some even saying that it is "infinitely close", they are not ready to say that it is equal to1. Richman (1999) discusses how "this argument gets its force from the fact that most people have been indoctrinated to accept the first equation without thinking", but also suggests that the argument may lead skeptics to question this assumption.

Changing [1-9] after the decimal point in the second option to [0-9] allows 7.0 to be matched, where it previously would not A common objection to 0.999… equalling 1 is that, while 0.999… may "get arbitrarily close to" 1, it is never actually equal to 1. But what is meant by the phrase "gets arbitrarily close to"? It's not like the number is moving at all; it is what it is, and it just sits there, blinking at you. It doesn't come or go; it doesn't move or get close to anything.When I say " 0.9999…", I don't mean 0.9 or 0.99 or 0.9999 or 0.999 followed by some large but finite (that is, some large but limited) number of 9's. The ellipsis (that is, the "dot, dot, dot") after the last 9 in 0.999… means "this goes on forever in the same manner". Discussion on completeness: I honestly didn't understand what it meant, but in the next paragraph it says the previous paragraph isn't proof. displaystyle 0.999\ldots =9\left({\tfrac {1}{10}}\right)+9\left({\tfrac {1}{10}}\right)

All of the following will match: 0, 1.1, 1.0, 1.9, 2.0, 2.1, 9.0, 9.1, 9.9, 10.0, but all of the following will not: 0.1, 0.2, 0.9, 1.11, 1.20, 1.01, 10.05, 110.05. Does not require one-number per line, can extract numbers embedded in text.For example, Minecraft 1.0.9 users can visit End City. This structure consists of several towers. There are the shulkers who live in this area. These aggressive creatures shoot shells with the effect of levitation. Many motherboard makers who are offering AM5 products showed excitement surrounding the launch of the new APUs after such a long time but it remains to be seen if AMD will keep those chips open for DIY customers or limit them to OEMs once again. The rumors also point out that the APUs will ship with 65W TDPs. More generally, every nonzero terminating decimal has two equal representations (for example, 8.32 and 8.31999...), which is a property of all positional numeral system representations regardless of base. The utilitarian preference for the terminating decimal representation contributes to the misconception that it is the only representation. For this and other reasons—such as rigorous proofs relying on non-elementary techniques, properties, or disciplines—some people can find the equality sufficiently counterintuitive that they question or reject it. This has been the subject of several studies in mathematics education.
