👉 Eliminators are mathematical symbols used to represent certain properties of a function or an expression. They serve as placeholders for values that might not be explicitly known, but can be calculated from other terms in the expression. For example, if you have a function f(x) = 3x^2 + 4x - 5 and you want to find x where f(x) is zero, you would set the derivative of f(x), which is 6x + 4 equal to zero
