An "almost integer" typically refers to a number that is very close to an integer but not exactly one. In various mathematical contexts, this concept can arise in discussions of numerical approximations, rounding, or certain sets of numbers that are nearly whole but slightly off. For example, numbers like 4.999, 2.001, or -3.9999 are considered almost integers because they are very close to the integers 5, 2, and -4, respectively.
The number 99 is a natural number that follows 98 and precedes 100. It is an integer, an odd number, and can be expressed in various numeric systems: - In Roman numerals, it is represented as XCIX. - In binary, it is written as 1100011. - In hexadecimal, it is represented as 63. Mathematically, 99 is the square of 9.
The number 999 is a natural number that follows 998 and precedes 1000. It is an integer and is considered a three-digit number.

The number 95 is an integer that comes after 94 and before 96. In various contexts, it can have different meanings: 1. **Mathematical Properties**: - It is an odd number. - It is a composite number, as it can be divided by 1, 5, 19, and 95. - Its prime factorization is \(5 \times 19\).
The number 94 is an integer that follows 93 and precedes 95. It is an even number, and in terms of its properties, it can be expressed as: - **Prime factorization**: \( 94 = 2 \times 47 \) (where both 2 and 47 are prime numbers). - **In Roman numerals**: 94 is represented as XCIV.
The number 93 is an integer that follows 92 and precedes 94. It is an odd number and can be described as a composite number, as it can be divided by 1, 3, 31, and 93. In Roman numerals, it is represented as XCIII.
The number 92 is an integer that follows 91 and precedes 93.
The number 91 is an integer that comes after 90 and before 92. It is an odd number and can be factored into prime factors as \( 7 \times 13 \). Additionally, 91 has various properties in mathematics: 1. **Mathematical Properties**: - It is a composite number. - It is the sum of the prime numbers 43 and 47.
The number 911 is an emergency telephone number used in the United States and several other countries to enable the public to make a quick request for emergency assistance from police, fire, or medical services. When someone dials 911, the call is routed to a local emergency dispatcher who can send the appropriate response teams to the caller's location.
The number 90 is an integer that follows 89 and precedes 91. It is a composite number, meaning it has divisors other than 1 and itself. Specifically, the divisors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
The number 900 is a three-digit integer that comes after 899 and before 901. It is an even number and can be expressed in several different mathematical contexts: 1. **Mathematical Properties**: - It is a composite number, meaning it has factors other than 1 and itself.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
