2. Inversion (music) - Wikipedia

   en.wikipedia.org/wiki/Inversion_(music)

   That is, when the first goes up, the second goes down the same number of diatonic steps (with some chromatic alteration); and when the first goes down, the second goes up the same number of steps. In music theory, an inversion is a rearrangement of the top-to-bottom elements in an interval, a chord, a melody, or a group of contrapuntal lines of ...

3. Ternary numeral system - Wikipedia

   en.wikipedia.org/wiki/Ternary_numeral_system

   A ternary / ˈtɜːrnəri / numeral system (also called base 3 or trinary) has three as its base. Analogous to a bit, a ternary digit is a trit ( tri nary dig it ). One trit is equivalent to log 2 3 (about 1.58496) bits of information . Although ternary most often refers to a system in which the three digits are all non–negative numbers ...

4. Floating-point arithmetic - Wikipedia

   en.wikipedia.org/wiki/Floating-point_arithmetic

   The base determines the fractions that can be represented; for instance, 1/5 cannot be represented exactly as a floating-point number using a binary base, but 1/5 can be represented exactly using a decimal base (0.2, or 2 × 10 −1). However, 1/3 cannot be represented exactly by either binary (0.010101...) or decimal (0.333...), but in base 3 ...

5. Cantor set - Wikipedia

   en.wikipedia.org/wiki/Cantor_set

   Numbers of the form 0.0xxxxx... 3 (including 0.022222... 3 = 1/3) Numbers of the form 0.2xxxxx... 3 (including 0.222222... 3 = 1) This can be summarized by saying that those numbers with a ternary representation such that the first digit after the radix point is not 1 are the ones remaining after the first step.

6. Computational complexity of mathematical operations - Wikipedia

   en.wikipedia.org/wiki/Computational_complexity...

   The following tables list the computational complexity of various algorithms for common mathematical operations . Here, complexity refers to the time complexity of performing computations on a multitape Turing machine. [ 1] See big O notation for an explanation of the notation used. Note: Due to the variety of multiplication algorithms, below ...

7. Nashville Number System - Wikipedia

   en.wikipedia.org/wiki/Nashville_Number_System

   The Nashville Number System is a method of transcribing music by denoting the scale degree on which a chord is built. It was developed by Neal Matthews Jr in the late 1950s as a simplified system for the Jordanaires to use in the studio and further developed by Charlie McCoy. [ 1] It resembles the Roman numeral [ 2] and figured bass systems ...
