👉 In mathematics, interposition is a special type of operation that involves placing one value before another in an expression. It is often used to simplify mathematical expressions and manipulate them in a way that makes them easier to work with. For example, consider the equation: \[ x + y - z \] If we want to simplify this expression by interposing \(x\) after \(y\), we can do so as follows: \[ x + (y - z) \] This operation is known as
