Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. 1 / 8 = 1 / 2 3 . In Unicode, precomposed fraction characters are in the Number Forms block.
In mathematics articles, fractions should always be written either with a horizontal fraction bar (as in ), or with a forward slash and with the baseline of the numbers aligned with the baseline of the surrounding text (as in 1/2). The use of {} (such as 1 ⁄ 2) is
Radical 8 or radical lid (亠部), whose meaning as an independent word is unknown, but is often interpreted to be a "lid" when used as a radical, is radical 23 of the 214 Kangxi radicals and consists of two strokes. In the Kangxi Dictionary, there are 38 characters (out of 49,030) to be found under this radical.
Division is also not, in general, associative, meaning that when dividing multiple times, the order of division can change the result. [7] For example, (24 / 6) / 2 = 2, but 24 / (6 / 2) = 8 (where the use of parentheses indicates that the operations inside parentheses are performed before the operations outside parentheses).
