👉 Eluents are a type of mathematical expression used in calculus to represent functions that can be expressed as the sum or difference of two simpler expressions. They are named after their ability to simplify algebraic expressions, which is similar to how a "completing the square" method can help us solve quadratic equations by breaking them down into simpler terms. Eluents have a special property where they can be represented using only addition and multiplication operations on variables. For example, consider the function f(x)
