An interjection is a word or expression that occurs as an utterance on its own and expresses a spontaneous feeling, situation or reaction. [1] [2] It is a diverse category, encompassing many different parts of speech, such as exclamations (ouch!, wow!
Elementary mathematics, also known as primary or secondary school mathematics, is the study of mathematics topics that are commonly taught at the primary or secondary school levels around the world. It includes a wide range of mathematical concepts and skills, including number sense , algebra , geometry , measurement , and data analysis .
For example, the interjection word indicating agreement is characteristic of African-American English. [27] Two examples of variation over time can be seen in the Corpus of Historical American English, which shows that nay was among the most common interjections in 1820 but by the 2010s had become significantly less common.

Equivalence class: given an equivalence relation, [] often denotes the equivalence class of the element x. 3. Integral part : if x is a real number , [ x ] {\displaystyle [x]} often denotes the integral part or truncation of x , that is, the integer obtained by removing all digits after the decimal mark .
A result is called "deep" if its proof requires concepts and methods that are advanced beyond the concepts needed to formulate the result. For example, the prime number theorem — originally proved using techniques of complex analysis — was once thought to be a deep result until elementary proofs were found. [1]
) Similarly, Greek rappers will use it along with the interjection man! as in "Re man". In the Greek American community of Tarpon Springs, Florida, a variation of the word is used with the same meaning. Instead of the term re, with the rolling of the "r" being said, the Greeks there say "ray", with no rolling of the "r".
Mathematics is a broad subject that is commonly divided in many areas or branches that may be defined by their objects of study, by the used methods, or by both. For example, analytic number theory is a subarea of number theory devoted to the use of methods of analysis for the study of natural numbers. This glossary is alphabetically sorted.
