```pwn
from pwn import *
r= remote("140.134.25.138",20000)
for i in range (0,100):
data = r.recvline().split()
result = 0;
if(data[1]=="+"):
result = int(data[0])+int(data[2])
elif(data[1]=="-"):
result = int(data[0])-int(data[2])
elif(data[1]=="*"):
result = int(data[0])*int(data[2])
r.sendline(str(result))
print r.recvline()
```
