  2. 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

    For 2 ≤ b ≤ 9 the numerical order of the numbers is the lexicographical order with n as the most significant number, so for the numbers of these 8 columns the numerical order is simply line-by-line.

  4. 100,000,000 - Wikipedia

    en.wikipedia.org/wiki/100,000,000

    100,000,000 (one hundred million) is the natural number following 99,999,999 and preceding 100,000,001.. In scientific notation, it is written as 10 8.. East Asian languages treat 100,000,000 as a counting unit, significant as the square of a myriad, also a counting unit.

    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.

    The highest numerical value banknote ever printed was a note for 1 sextillion pengő (10 21 or 1 milliard bilpengő as printed) printed in Hungary in 1946. In 2009, Zimbabwe printed a 100 trillion (10 14) Zimbabwean dollar note, which at the time of printing was worth about US$30. [13]

    A standardized way of writing very large numbers allows them to be easily sorted in increasing order, and one can get a good idea of how much larger a number is than another one. To compare numbers in scientific notation, say 5×10 4 and 2×10 5, compare the exponents first, in this case 5 > 4, so 2×10 5 > 5×10 4.

    en.wikipedia.org/wiki/Computational_complexity...

    The elementary functions are constructed by composing arithmetic operations, the exponential function (), the natural logarithm (), trigonometric functions (,), and their inverses. The complexity of an elementary function is equivalent to that of its inverse, since all elementary functions are analytic and hence invertible by means of Newton's ...
