Overflow in serial.print

Using Arduino Programming Questions
1

Dear friends,
L faced a strange problem in Arduino, and at the end I find that

Serial.println(1*60*1000);

prints :
-5536
I find this happens for all answers greater than 32,767 which is the MAX range of "int" variable !
what the problem ?
and how can I solve it ?

try
Serial.println(1ul*60*1000);
to make it a unsigned long

BTW this is nothing to do with print. Its because ints are 16 bit unless you cast to long.
