Project (Help on while loop)

Question

Hello, for this program two students must enter a symbol to generate a random math problem, however, i have attempted to input to where if both students got it correct, itll output theyre both correct and the program will start over, I also want this to apply if they both got the math problem incorrect but when I enter two correct answers or two incorrect answers itll input both player 1 and player 2 getting the win or point, how can i make it so that itll ONLY output if both are correct when both get the right answer as well as how to output so it ONLY says theyre incorrect if both answers given are wrong?

Answer 1

Please look at case (+) for example, I will apply that to (-) and (*)
