    A formula is often implicitly provided in the form of a computer instruction such as. Degrees Celsius = (5/9)*(Degrees Fahrenheit - 32) In computer spreadsheet software, a formula indicating how to compute the value of a cell, say A3, could be written as =A1+A2. where A1 and A2 refer to other cells (column A, row 1 or 2) within the spreadsheet.

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

    For example, ethanol may be represented by the condensed chemical formula CH 3 CH 2 OH, and dimethyl ether by the condensed formula CH 3 OCH 3. These two molecules have the same empirical and molecular formulae ( C 2 H 6 O ), but may be differentiated by the condensed formulae shown, which are sufficient to represent the full structure of these ...

    en.wikipedia.org/wiki/Mathematical_notation

    Mathematical notation is widely used in mathematics, science, and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. For example, the physicist Albert Einstein 's formula E = m c 2 {\displaystyle E=mc^{2}} is the quantitative representation in mathematical notation of mass–energy ...
