The word in its various forms is derived from the Arabic _al-Khowarazmi_ (i.e. the native of Khwarazm (Khiva)). This was the surname of Ja’far Mohammad ben Musa, who wrote a treatise early in the 9th century (see p. xiv). The form _algorithm_ is also found, being suggested by a supposed derivation from the Greek ἀριθμός (number). +antery+, 24/11; to move figures to the right of the position in which they are first written. This operation is performed repeatedly upon the multiplier in multiplication, and upon certain figures which arise in the process of root extraction. +anterioracioun+, 50/5; the operation of moving figures to the right. [[written anteriorac{i}o{u}n or anterioracio{u}n]] +article+, 34/23; +articul+, 5/31; +articuls+, 9/36, 29/7,8; a number divisible by ten without remainder. [[also articull{e}]] +cast+, 8/12; to add one number to another. ‘Addition is a _casting_ together of two numbers into one number,’ 8/10. +cifre+, 4/1; the name of the figure 0. The word is derived from the Arabic _sifr_ = empty, nothing. Hence _zero_. A cipher is the symbol of the absence of number or of zero quantity. It may be used alone or in conjunction with digits or other ciphers, and in the latter case, according to the position which it occupies relative to the other figures, indicates the absence of units, or tens, or hundreds, etc. The great superiority of the Arabic to all other systems of notation resides in the employment of this symbol. When the cipher is not used, the place value of digits has to be indicated by writing them in assigned rows or columns. Ciphers, however, may be interpolated amongst the significant figures used, and as they sufficiently indicate the positions of the empty rows or columns, the latter need not be indicated in any other way. The practical performance of calculations is thus enormously facilitated (see p. xvi). +componede+, 33/24; +composyt+, 5/35; with reference to numbers, one compounded of a multiple of ten and a digit. [[written componed{e}]] +conuertide+ = conversely, 46/29, 47/9. [[written co{n}u{er}tid{e} or {con}u{er}tid{e}]] +cubicede+, 50/13; +to be c.+, to have its cube root found. [[written cubiced{e}]] +cubike nombre+, 47/8; a number formed by multiplying a given number twice by itself, _e.g._ 27 = 3 × 3 × 3. Now called simply a cube. [[written cubik{e} ...]] +decuple+, 22/12; the product of a number by ten. Tenfold. +departys+ = divides, 5/29. [[written dep{ar}tys]]
