Question

mathTutor Write a program that selects two random numbers -20 to 20. The two numbers would get displayed with "+" between them. The user should enter the sum of the two numbers. The program should print "Incorrect" if the user enters a wrong answer and re-prompts the user to re-enter the answer again. Limit the number of incorrect tries to 3. After 3 incorrect tries print the correct answer. The program should print a message like "Correct!" if the user enters the right answer. The program would then display "Would you like another problem y/n? ". If user selects "y" or "Y" you show them another problem to be solved. (JAVA)
