String new1 = Integer.toString(result1);
String new2 = Integer.toString(result2);
String new3 = Integer.toString(result3);
String new4 = Integer.toString(result4);

String newNN = New1 + New2 + New3 + New4;
Int newN = Integer.parseInt(newNN);
int firstAnswer = newNN + m ;

String firstAnswer2 = Integer.toString(firstAnswer);
String finalAnswer = Character.toString(firstAnswer2.charAt(0));
String finalAns1 = Character.toString(firstAnswer2.charAt (1));
String finalAns2 = Character.toString(firstAnswer2.charAt (2));
String finalAns3 = Character.toString(firstAnswer2.charAt (3));
String finalAns4 = Character.toString(firstAnswer2.charAt (4));
String newNN = finalAns1 + finalAns2 + finalAns3 + finalAns4;

Int newN2 = Integer.parseInt(newNN2);
Int newN3 = Integer.parseInt(finalAnswer);
Ins Answer = newN2 + newN3;
