Write two numbers. It will caculate the total at ' Tổng ' Well, I use this like a caculator. And renember, It just use for addition. Make sure to first number and second number is < 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 I think this number can caculate over a trilion mutiply by a trilion :)))
