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,b,c,d = list(input())

ls = ["+"] * 3

print(ls)

for i in range(2**3):
    ls = ["+"] * 3
    for j in range(len(ls)):
        
        if (i >> j) & 1:
            ls[j] = "-"

    if eval(a+ls[0]+b+ls[1]+c+ls[2]+d) == 7:
        print(a+ls[0]+b+ls[1]+c+ls[2]+d+"=7")
        break
        
a,b,c,d = list(input())
