Sitting in a station waiting room, Joisino is gazing at her train ticket.  The ticket is numbered with four digits A, B, C and D in this order, each between 0 and 9 (inclusive).  In the formula A op1 B op2 C op3 D = 7, replace each of the symbols op1, op2 and op3 with `+` or `-` so that the formula holds.  The given input guarantees that there is a solution. If there are multiple solutions, any of them will be accepted.
A = list(map(int, list(input())))

for i in range(1 << 3):
    x = A[0]
    ans = str(A[0])
    for j in range(3):
        if i & 1 << j > 0:
            x += A[j + 1]
            ans += '+' + str(A[j + 1])
        else:
            x -= A[j + 1]
            ans += '-' + str(A[j + 1])
    if x == 7:
        print(ans)
        break
