### written language | notation:

Exponential notation
* combines the angle and axis of the rotation into concise quaternion expression.
* convenient way for scientists to write very large or very small numbers.
* is an example of a shorthand notational scheme
  - used on many calculators and programming languages
  - useful in situations where the same number is multiplied repeatedly
* method of expressing a square number by using a base and an exponent.
* way scientists write very large or very small numbers.

Figurine notation
* is used in print and computer chess.
+ Chess notation, Algebraic notation, Figurine notation: Chess :: Notation
  * This is algebraic notation with little figurines instead of initial letters for the pieces. Figurine notation is used in print and computer chess. Since it avoids initial letters for pieces, it is more international.

Hexadecimal notation
* convenient way of representing the values in a byte with two characters.
* is mathematical notation

Mathematical notation
* Some mathematical notations use diagrams , or small drawings to show the underlying concepts
  - diagrams, or small drawings to show the underlying concepts. * diagrams, or small drawings to show the underlying concepts. One example is the Penrose graphical notation which is used to show tensors
* is notation.

### written language | notation | mathematical notation:

Binary system
* All binary systems contain an unseen low-mass component, presumably, a white dwarf.
* Many binary systems involve neutron stars.
* Most binary systems are too distant to be resolved as visuals by current telescopes.
* are important because they allow astronomers to determine the masses of stars.
* detected by such astrometric means are called astrometric binaries.
* offer unique methods to understand stellar activity and mass loss.

Decimal point
* are mathematical notation.
* is mathematical notation

Number system
* come in many sizes.
* serve the purpose of representing numbers in different ways.

Musical notation
* highly developed symbolic language, in which symbols represent ideas.
* is also an informal language as is the set of conventions used in a road map
  - part of scores
  - the international language that spans all instruments

### written language | notation:

Scientific notation
* Scientific Notation Explains how scientific notation is used to manipulate very large numbers
  - makes adding, subtracting, multiplying and dividing numbers much simpler
* allows very large or very small numbers to be written in a more convenient form
  - writing big and small numbers with only a few symbols
* is the standard mantissa E exponent form used in most languages.
* is used in different contexts to express extremely large and very small numbers
  - more operations and with real-life problems
  - to track the decimal point in more formal calculations
* makes it easy to express how precisely a number is known.
* represents numbers as a base number and an exponent.
* shorthand for writing very small and very large numbers.
* works on the basis of exponents.
+ Slide rule, Basic concepts: Mathematical tools
  * The user determines the location of the decimal point in the result, based on mental estimation. Scientific notation is used to track the decimal point in more formal calculations. Addition and subtraction steps in a calculation are generally done mentally or on paper, not on the slide rule.

Spectroscopic notation
* is based on facts taken from molecular symmetry.
+ Molecular symmetry: Symmetry :: Theoretical chemistry
  * Scientists can find molecular symmetry by using X-ray crystallography and other forms of spectroscopy. Spectroscopic notation is based on facts taken from molecular symmetry.

Vector notation
* is simply a short-hand way of expressing information in a compact but precise way.
* requires working knowledge of trigonometry.
