Math arithmetic operator

Here, the math operator is:-
 
  " + "   (Addition)
  " – "   (Subtraction)

  " * "  (Multiplication)
  " / " (Division)

  " %"  (Modulus)

Example:-
public class math;
{
public static void main(string[]  arg)
{
int x,y,answer;
x=60;
y=30;
answer=x+y;   //(perform add operation)
answer=x-y;    //(perform sub operation)
answer=x*y;   //(perform mul operation)
answer=x/y;    //(perform div operation)
answer=x%y;  //(perform mod operation)

System.out.println(“Answer of addition =”+ answer);
}
}
