PD:
Actually, the parseInt part is not needed if you are going to manipulate the
input as text...
So, you can change this line:
resultTxt.text = (parseInt(ageField.text) + inputChar).toString();
to:
resultTxt.text = ageField.text + inputChar;
Since parseInt(ageField.text) is converted to a string anyway before being
concatenated to inputChar.
You should also restrict the input text to accept only numbers or validate
the input by yourself.
