In mathematics, an algebraic expression is an expression built up from constants (usually, algebraic numbers) variables, and the basic algebraic operations: addition (+), subtraction (-), multiplication (×), division (÷), whole number powers, and roots (fractional powers).
Examples of unexpected applications of mathematical theories can be found in many areas of mathematics. A notable example is the prime factorization of natural numbers that was discovered more than 2,000 years before its common use for secure internet communications through the RSA cryptosystem. [127]

In expository writing, a topic sentence is a sentence that summarizes the main idea of a paragraph. [1] [2] It is usually the first sentence in a paragraph. Also known as a topic sentence should encapsulate or organize a entire paragraph. Although topic sentences may appear anywhere in a paragraph, in academic essays they often appear at the ...
Its mathematical content consists of rules and examples, written in verse, together with prose commentaries, which include solutions to the examples. [63] The topics treated include arithmetic (fractions, square roots, profit and loss, simple interest, the rule of three , and regula falsi ) and algebra (simultaneous linear equations and ...
A paragraph (from Ancient Greek παράγραφος (parágraphos) 'to write beside') is a self-contained unit of discourse in writing dealing with a particular point or idea. Though not required by the orthographic conventions of any language with a writing system , paragraphs are a conventional means of organizing extended segments of prose .
The term 'expression' is part of the language of mathematics, that is to say, it is not defined within mathematics, but taken as a primitive part of the language. To attempt to define the term would not be doing mathematics, but rather, one would be engaging in a kind of metamathematics (the metalanguage of mathematics), usually mathematical logic.
