👉 Palliations are a type of mathematical expression used to simplify expressions by replacing variables or numbers with their equivalent in terms of smaller, more familiar quantities. They are often used in algebra and calculus to make complex calculations simpler. For example, consider the expression: \[ 2x + 3y \] We can substitute \( x = y \) into the expression to get: \[ 2y + 3y \] This simplifies to: \[ 5y \] So,
