The use of Roman numerals continued long after the decline of the Roman Empire.From the 14th century on, Roman numerals began to be replaced by Arabic numerals; however, this process was gradual, and the use of Roman numerals persisted in various places, including on clock faces.
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]
88 is: . a refactorable number. [1]a primitive semiperfect number. [2]an untouchable number. [3]a hexadecagonal number. [4]an Erdős–Woods number, since it is possible to find sequences of 88 consecutive integers such that each inner member shares a factor with either the first or the last member.
Roman numerals: The numeral system of ancient Rome, still occasionally used today, mostly in situations that do not require arithmetic operations. Tally marks: Usually used for counting things that increase by small amounts and do not change very quickly. Fractions: A representation of a non-integer as a ratio of two integers.
888 is a practical number, meaning that every positive integer up to 888 itself may be represented as a sum of distinct divisors of 888. [2] 888 is equal to the sum of the first two Giuga numbers: 30 + 858 = 888. [3] There are exactly: 888 trees with four unlabeled and three labeled nodes, [4] 888 seven-node undirected graphs without isolated ...
Sexagesimal numerals were a mixed radix system that retained the alternating bases of 10 and 6 that characterized tokens, numerical impressions, and proto-cuneiform numerical signs. Sexagesimal numerals were used in commerce, as well as for astronomical and other calculations.
Roman numerals, the Brahmi and Chinese numerals for one through three (一 二 三), and rod numerals were derived from tally marks, as possibly was the ogham script. [7] Base 1 arithmetic notation system is a unary positional system similar to tally marks. It is rarely used as a practical base for counting due to its difficult readability.
The Latin numerals are the words used to denote numbers within the Latin language. They are essentially based on their Proto-Indo-European ancestors, and the Latin cardinal numbers are largely sustained in the Romance languages. In Antiquity and during the Middle Ages they were usually represented by Roman numerals in writing.
