Equivalent definitions could be presented utilizing μ-recursive functions, Turing equipment or λ-calculus. The computable numbers are secure for all typical arithmetic operations, including the computation of the roots of the polynomial, and so sort an actual closed industry which contains the actual algebraic numbers.
