oper = input("输入运算符号（目前只支持+/-）")
if (oper == "+"):
    maxlen = [input(),input()]
    a, b = map(int, maxlen)
    r = a + b
    maxlen.append(str(r))
    maxlen = max(len(s) for s in maxlen)
    print(f'{a:>{maxlen+4}d}')
    print(f'{"+":>3s}{b:>{maxlen+1}d}')
    print(f'{"-"*(maxlen+4):>{maxlen+5}s}')
    print(f'{r:>{maxlen+4}d}')
elif oper == "-":
    maxlen = [input(), input()]
    a, b = map(int, maxlen)
    r = a - b
    maxlen.append(str(r))
    maxlen = max(len(s) for s in maxlen)
    print(f'{a:>{maxlen+4}d}')
    print(f'{"-":>3s}{b:>{maxlen+1}d}')
