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.
ary = list(map(int, input()))


for i in range(1 << 3):
    tmp = ary[0]
    ans = str(ary[0])
    for j in range(3):
        if i & (1<<j):
           tmp += ary[j+1]
           ans+= "+" + str(ary[j + 1])
        else:
            tmp -= ary[j+1]
            ans+= "-" + str(ary[j + 1])

    if tmp == 7:
        print(ans)
        break
