title: Big Integer looping number calculation
body: <p>Does anyone know why does it only run the code once and not every time the button is clicked? As a result, it always shows 12</p>
  
  <pre><code>        @Override
          public void onClick(View v) {
              BigInteger example1 = new BigInteger("120");
              BigInteger example2 = new BigInteger("100");
  
              BigInteger example3 = new BigInteger("10");
  
              example3 = (example3.multiply(example1).divide(example2));
  
              String example4 = String.valueOf(example3);
  
              testb.setText(example4);
          }
      });
