Numbers can be written as words (for example, one hundred) or as numerals (e.g., 100). In this paper, we adhere to the requirements of APA Style, one of the most widely used style guides in academic writing. In general, words should be used for numbers 0 through 9, while numerals should be used for numbers 10 and up. You should not use words to represent numbers over ten, since many formats (such as newspaper articles) limit how many characters you can use.
In scientific papers, numbers are usually presented in text form with numerals, rather than by spelling out words (for example, "seven" instead of "7"). This is because numerals are easier to read when they are close together. When writing about data that includes numbers over 10, they should be presented by numerals.
When writing about percentages, it is customary to use per cents rather than percent signs. For example, instead of saying "20% of students failed the exam," say "80% of students passed the exam." Percentages should be written in full sentences rather than as fractions - for example, "John passes the exam 80% of the time."
When writing about money, dollars are normally spelled out whereas euros use symbols. For example, "$10,000" but "€8,333".
For dates, months are always written out in full, for example, January, February, March... December.
In nontechnical writing, it is often better to write numbers from 0 to 100. The dominant technique in scientific and technical writing is to write out numbers less than 10. For example, a reference might say "fifty-two" or "52." This is because scientists and engineers write about concepts, not people or things. They use numbers as tools to describe phenomena and predict outcomes. Thus, they rarely use first-, second-, or third-person pronouns to refer to numbers.
In academic essays, numbers are usually spelled out unless they are zero or one. In that case, the word "zero" or "one" should be used instead. For example, "my score on the test was zero" or "the score on this exam was one."
It is acceptable to use lowercase letters for numbers from 1 to 9. After that, numbers become nouns and are usually capitalized. So, "10,000 dollars" is correct but "ten thousand dollars" is not. "$10,000" can also be written as "10 000" or "$10,000".
Round figures, such as hundreds, thousands, or hundred thousand, should be typed out completely. Written fractions are difficult to read and understand.
In general, spelling words out is acceptable for informal letters, but not for formal documents such as essays and reports. Using abbreviations instead is also acceptable for informal letters, but not for formal documents.
Numbers greater than ten can be written in ordinary text as long as there's a way to identify them easily. For example, "The most common blood type is O, followed by A, B, and AB." Or you could use numbered lists: "Type O blood is the most common blood type followed by Type A, B, and AB." Either method is acceptable.
You can also write out numbers from 1 to 10 directly in your document if there's room for confusion about which number you're referring to. In this case, it's clear that John had no phone number because he needed to be contacted via email or in person.
A simple rule for utilizing numbers in writing is to spell out little numbers ranging from one to ten (or one to nine, depending on the style guide). Larger numbers (those more than 10) are written as numerals. Numbers play an important role in any writing sample or test score.
Numbers help to clarify your thoughts on a topic and provide support for your arguments. They can also be used to enhance the readability of your text by breaking up long sentences. This will help readers avoid feeling overwhelmed by dense prose!
As you can see, numbers have many uses in writing. It's helpful if you know how to utilize them properly.
Making Small and Big Numbers A simple rule for utilizing numbers in writing is to spell out little numbers ranging from one to ten (or one to nine, depending on the style guide). For example, 1 million is written as one million, not one thousand million.
When writing about a large or small number, it is customary to use numbers in words rather than symbols. For example, "few" instead of φ (phi), "some" instead of λ (lambda), "many" instead of μ (mu), etc.
In mathematics and science, numbers often appear in formulas where they are expressed in words rather than symbols. For example, the formula for finding the sum of an arithmetic sequence reads:
Where T is the number of terms in the sequence and n is the difference between each term.
Fundamental numbers Numbers up to nine should always be expressed in words, whereas numbers more than nine can be written in numerals. For example, you would say "I went to the store to buy some food" not "I went to the stores to buy some food"; similarly, you would say "Three people went to the movie" not "Three people went to the movie."
Fractions and decimals Fractions and decimals are both expressed as numbers with a fraction or decimal point before them. For example, 1/2 is also known as half, and 7.5 is also known as seven and a quarter. Decimals must be divided by 10 to find their whole number equivalent; for example,.15 is equal to one-fifth. Divisibility by any integer other than 0 or 10 is used to determine whether a fraction or decimal is acceptable. For example, if someone asked you why there were no flowers on the assignment sheet, you could say "The teacher did not give us permission to leave assignments out for people to pick up," because it's possible that person is a murderer who does not like you.
Rounding Rounding is the process of making calculations less precise.
