👉 Presumers are a type of mathematical object that is defined by a single equation or inequality. They are used to simplify complex algebraic expressions and make them easier to work with. Presumers can be thought of as "small" variables that represent small quantities, and they allow for the simplification of large equations or inequalities. Presumers have applications in fields such as physics, engineering, and computer science, where they are used to solve complex problems and find solutions more efficiently.
