A mixed number (also called a mixed fraction or mixed numeral) is the sum of a non-zero integer and a proper fraction, conventionally written by juxtaposition (or concatenation) of the two parts, without the use of an intermediate plus (+) or minus (−) sign. When the fraction is written horizontally, a space is added between the integer and ...
Covers the ten decimal digits and all letters of the English alphabet, apart from not distinguishing 0 from O. 36: Hexatrigesimal [57] [58] Covers the ten decimal digits and all letters of the English alphabet. 37: Covers the ten decimal digits and all letters of the Spanish alphabet. 38: Covers the duodecimal digits and all letters of the ...
In this cipher, a 5 x 5 grid is filled with the letters of a mixed alphabet (two letters, usually I and J, are combined). A digraphic substitution is then simulated by taking pairs of letters as two corners of a rectangle, and using the other two corners as the ciphertext (see the Playfair cipher main article for a diagram). Special rules ...
[6] [2] [7] In some specialized contexts, the word decimal is instead used for this purpose (such as in International Civil Aviation Organization-regulated air traffic control communications). In mathematics, the decimal separator is a type of radix point , a term that also applies to number systems with bases other than ten.
Notation for fractions other than 1 ⁄ 2 is mainly found on surviving Roman coins, many of which had values that were duodecimal fractions of the unit as. Fractions less than 1 ⁄ 2 are indicated by a dot ( · ) for each uncia "twelfth", the source of the English words inch and ounce ; dots are repeated for fractions up to five twelfths.
In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using ...
The first letter(s) of the word to be abbreviated are followed by a period; then, the final letter(s) of the word are written as lowercase superscripts. This gives the abbreviations n. o (singular) and n. os (plural). The abbreviation "no." is not used (it might be mistaken for the Spanish negative word no). The abbreviations nro. and núm. are ...

For instance, socialism may refer to an economic system, or it may refer to an ideology that supports that economic system. The same term may also refer to multiple ideologies, which is why political scientists try to find consensus definitions for these terms.
