    He defines the lexicographical order and an addition operation, noting that 0.999... < 1 simply because 0 < 1 in the ones place, but for any nonterminating ⁠ ⁠, one has 0.999... + = 1 + ⁠ ⁠. So one peculiarity of the decimal numbers is that addition cannot always be canceled; another is that no decimal number corresponds to ⁠ 1 3 ...

  3. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    The order of operations, that is, the order in which the operations in an expression are usually performed, results from a convention adopted throughout mathematics, science, technology and many computer programming languages. It is summarized as: [2] [5] Parentheses; Exponentiation; Multiplication and division; Addition and subtraction

  4. 999 (number) - Wikipedia

    en.wikipedia.org/wiki/999_(number)

    In some parts of the world, such as the UK and Commonwealth countries, 999 (pronounced as 9-9-9) is the emergency telephone number. 999 was a London punk band active during the 1970s. 999 is also the short name for the visual novel Nine Hours, Nine Persons, Nine Doors. 999 is the last 3 digit number. It is also the last number in English ...

  5. Order of magnitude - Wikipedia

    en.wikipedia.org/wiki/Order_of_magnitude

    Order of magnitude is a concept used to discuss the scale of numbers in relation to one another. Two numbers are "within an order of magnitude" of each other if their ratio is between 1/10 and 10. In other words, the two numbers are within about a factor of 10 of each other. [1] For example, 1 and 1.02 are within an order of magnitude.

    In this case, in the first decimal representation, all are zero for >, and, in the second representation, all 9. (see 0.999... for details). In summary, there is a bijection between the real numbers and the decimal representations that do not end with infinitely many trailing 9.

  7. Normal order of an arithmetic function - Wikipedia

    en.wikipedia.org/wiki/Normal_order_of_an...

    In number theory, a normal order of an arithmetic function is some simpler or better-understood function which "usually" takes the same or closely approximate values. Let f be a function on the natural numbers. We say that g is a normal order of f if for every ε > 0, the inequalities

  8. Large numbers - Wikipedia

    en.wikipedia.org/wiki/Large_numbers

    A function with a vertical asymptote is not helpful in defining a very large number, although the function increases very rapidly: one has to define an argument very close to the asymptote, i.e. use a very small number, and constructing that is equivalent to constructing a very large number, e.g. the reciprocal.

  9. Completeness of the real numbers - Wikipedia

    en.wikipedia.org/wiki/Completeness_of_the_real...

    In the decimal number system, completeness is equivalent to the statement that any infinite string of decimal digits is actually a decimal representation for some real number. Depending on the construction of the real numbers used, completeness may take the form of an axiom (the completeness axiom), or may be a theorem proven from the construction.
