assignment for NOV21

I did the division summation and multiplication and subtraction functions :
Then I also added text for the result .
But I really got problem with  using them into textfields .
Following are screenshot for my sketch:

PFont fontA ;
PImage a ;

int divisionof2numbers ( int number1  , int number2 ) {

  int  division = 0;

  division =  number1 / number2 ;

  println ("the answer of division :" + number1 + " divide " + number2 + " = " + division );

  return division ;
}

void setup()
{
 a = loadImage ( "bg.png");
  size (400,400) ;
 background(a);

  int answer =  divisionof2numbers  ( 4444444 , 44 ) ;
   fontA = loadFont("Amoeba-Bold-48.vlw");
  textFont(fontA, 32) ;
  fill(0, 102, 153);
  String s = "The answer is :" + answer ;
  text ( s,50 , 200);
}
