fix the code so that we are able to do simple math operations on two numbers we enter and only two number if we enter text we should see a warning message and go back to entering the first number hint : + operation : 1- correct input [numbers only] => the result is not correct 2- false input [text] => the warning message does not appear and the result is always zero - operation : 1- correct input [numbers only] => The warning message appears whenever we enter a number and the result is never shown 2-false input [text] => We are able to enter text and the result is always zero
