2. Quinary - Wikipedia

   en.wikipedia.org/wiki/Quinary

   Quinary (base 5 or pental[1][2][3]) is a numeral system with five as the base. A possible origination of a quinary system is that there are five digits on either hand. In the quinary place system, five numerals (0, 1, 4, 7, and 9), are used to represent any real number. As five is a prime number, only the reciprocals of the powers of five ...

3. Numeral system - Wikipedia

   en.wikipedia.org/wiki/Numeral_system

   A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number eleven in the decimal or ...

4. Scientific notation - Wikipedia

   en.wikipedia.org/wiki/Scientific_notation

   Converting a number from scientific notation to decimal notation, first remove the × 10 n on the end, then shift the decimal separator n digits to the right (positive n) or left (negative n). The number 1.2304 × 10 6 would have its decimal separator shifted 6 digits to the right and become 1,230,400 , while −4.0321 × 10 −3 would have its ...

   Mathematical notation consists of using symbols for representing operations, unspecified numbers, relations, and any other mathematical objects and assembling them into expressions and formulas. Mathematical notation is widely used in mathematics , science , and engineering for representing complex concepts and properties in a concise ...

9. Octal - Wikipedia

   en.wikipedia.org/wiki/Octal

   The octal representation is formed by the quotients, written in the order generated by the algorithm. For example, to convert 125 10 to octal: 125 = 8 2 × 1 + 61 61 = 8 1 × 7 + 5 5 = 8 0 × 5 + 0. Therefore, 125 10 = 175 8. Another example: 900 = 8 3 × 1 + 388 388 = 8 2 × 6 + 4 4 = 8 1 × 0 + 4 4 = 8 0 × 4 + 0. Therefore, 900 10 = 1604 8.
