The unknowns or variables
In typography, capital letters that are considered properties typically refer to the letters that signify certain functions or categories in various contexts. For example, in programming, capital letters might denote constants or specific classes. In mathematical notation, capital letters can represent sets or specific variables. Additionally, in certain formal writing styles, capital letters are used to denote proper nouns or the beginning of sentences.
Those letters are indeed often used to represent integers. But in practice, it's best to always check what assumptions are made. If certain variables (letters) are meant to be integers only, for example for some theorem, this should be stated explicitly.
They are replaced as letters.
To represent variables you don't know, or could be anything.
Basic Algebra is where letters called variables are used in place of numerals
Letters used in math are called variables.
