A pie chart showing the percentage by web browser visiting Wikimedia sites (April 2009 to 2012) In mathematics, a percentage (from Latin per centum 'by a hundred') is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign (%), [1] although the abbreviations pct., pct, and sometimes pc are also used. [2]
Year 100 was a leap year starting on Wednesday of the Julian calendar. The denomination 100 for this year has been used since the early medieval period.
Examples are firstly the Egyptian numerals, then the Brahmi numerals, Greek numerals, Hebrew numerals, Roman numerals, and Chinese numerals. [5] Very large numbers were difficult to represent in these old numeral systems, and only the best mathematicians were able to multiply or divide large numbers.
The 2, 8, and 9 resemble Arabic numerals more than Eastern Arabic numerals or Indian numerals. Leonardo Fibonacci was a Pisan mathematician who had studied in the Pisan trading colony of Bugia , in what is now Algeria , [ 15 ] and he endeavored to promote the numeral system in Europe with his 1202 book Liber Abaci :
In base 60, 4000 can be written as 1:6:40. [e] Because the Assyro-Babylonian system does not have a symbol separating the fractional and integer parts of a number [13] and does not have the concept of 0 as a number, [14] it does not specify the power of the starting digit. Accordingly, 1/54 can also be written as 1:6:40.
120 is . the factorial of 5, i.e., ! =.; the fifteenth triangular number, [2] as well as the sum of the first eight triangular numbers, making it also a tetrahedral number. 120 is the smallest number to appear six times in Pascal's triangle (as all triangular and tetragonal numbers appear in it).
One half is the rational number that lies midway between 0 and 1 on the number line. Multiplication by one half is equivalent to division by two, or "halving"; conversely, division by one half is equivalent to multiplication by two, or "doubling". A square of side length one, here dissected into rectangles whose areas are successive powers of ...
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
