👉 In mathematics, "precomposition" is a binary operation that takes two elements from a set and returns another element. This operation can be performed on any two elements in the set, regardless of their types or values. For example: - Precomposing 2 and 3 gives us 6. - Precomposing -1 and 5 gives us -6. Precomposition is often used to simplify expressions that involve complex numbers or other mathematical operations.
