### magnitude | amount | number:

Integer
* Every integer has a finite stopping time
  - is divisible by at least one prime number
  - rational number
* Some integers are perfect squares.
* are OK to count small numbers of things.
* are a built-in type
  - countable subset of the rational numbers and real numbers
  - all real whole numbers including positive and negative numbers
* are also rational numbers since they can be represented as fractions
  - capable of factoreds
  - distinct values from floating-point numbers
  - just positive or negative whole numbers
  - negative or positive whole numbers
  - neither true nor false
  - output as strings of digits, with a leading space or a negative sign
* are the finite ordinals
  - whole numbers, negative whole numbers, and zero
  - whole numbers, including negative numbers
* can also be short, and unsigned.
* consist of all of the numbers that have no decimal expansion.
* have no decimal part, whereas floating point numbers do
  - the usual values
* know arithmetic.
* offer a larger range than real numbers.
+ Real number, Different types of real numbers: Number theory
  * Integers consist of all of the numbers that have no decimal expansion. In other words, they have only zeros after their decimal, which we normally choose not to write. 0 is also an integer, even though it has no positive nor negative signs. Integers are a countable subset of the rational numbers and real numbers.

### magnitude | amount | number | integer:

Positive integer
* All positive integers are equal.
* Every positive integer has exactly one successor
  - is expressible as a product of prime numbers in a unique way
* are an infinite family whose kinship is wonderfully intricate
  - positive numbers
  - the numbers to the right of zero
* use the same representation as unsigned.

### magnitude | amount | number | integer:

Serial number
* are consecutive with all sizes and models of instruments running together
  - ids
  - important in the recovery of stolen property
  - in numerical order
* can be as many as a dozen digits long.
* is an integer.
+ Serial number, What are serial numbers used for?: Numbers
  * Serial numbers can be very useful for quality control. That way, if there is a problem with a certain batch of products, the serial number of one defective item can tell which items are affected by the problem. Serial numbers can also be used against stealing or imitating products, because it is possible to keep track of which serial numbers have been used. Stolen goods or those with problems can be identified more easily.

Low number
* occur when the sun is low in the sky and during overcast conditions.
* represent acidic substances, high numbers represent alkaline substances.

Majority
* Majorities are ages
  - both the blessing and the curse of democratic society
  - part of adulthood
* Majorities have characteristics
  - deficiencies
  - homology
  - ideas
  - physical characteristics
* Majorities have similar characteristics
  - live in regions
* Majorities occur during years
  - within weeks
  - present theories
  - support conclusions
* Most majorities live in regions.
* Some majorities have eyes.
* refers to having more than half.

Mite number
* can also decrease quickly with rainfall or predator activity.
* increase on the plant and they being to move upward to the newest growth.

Multiplier
* are numbers.
* measure the response of the economy to a change in demand or production.

Native number
* are used for numbers one through ten.
+ Waray-Waray, Sounds, Numbers: Austronesian languages
  * Native numbers are used for numbers one through ten. Some, specially the old ones, are spoken alongside the Spanish counterparts.

Natural number
* Every natural number is either prime or can be uniquely factored as a product of primes.
* are also whole numbers
  - finite cardinal numbers
