iphone - NSMutableArray integer storage -

I am trying to store numbers within NSMutableArray, and wrap them like this:

  - (IBAction) op: (ID) sender {opBool = YES; OpNum = [sender tag]; [NumArray addObject: [Number with number number: Number 2]]; [Op. Ad object: [NSNumber number withINT: opNum]]; Number 1 = 0; Number 2 = 0; OpNum = 0; NSLog (@ "Operate% i", opNum); NSLog (@ "% i,% i", numberarre coat, operatera coat); }   
 But when I use it later:  
  final2 = [numArray objectAtIndex: i]; Operating = [OPERATE ObjectExtends: I];   
 I get this error message:  
 
 operating par 111526320   
 not going out of 'operating' Is 20. Can anyone help me with this? Thank you.   
 
 
  operating = [[operar object atindex x: i] intuue];
