Homework Help: Forming a specific number with given numbers and operations

  1. May 31, 2012 #1
    Suppose you are given (1) a natural number N; (2) a set of natural num-
    bers S = {n1; n2; : : : }; (3) a set of arithmetic operators, say +; -;*; =
    (with the usual meaning of addition, multiplication, substraction, di-
    vision). Your job is to construct an arithmetic expression R built from
    the given operators and using each of the numbers in S exactly once,
    with R = N.
    (a) Explain in general how you could solve that problem.
    (b) Solve the speci c instance: N = 24, S = {1; 3; 4; 6}
