Which two statements are correct for arithmetic operations?

Answer 1

Please dont post questions of solutions for quizzes inside the courses here.
Each of these little quizzes can easily be solved by carefully reading through the lesson before the quiz itself, and in case you have absolutly no idea, you still can use some of your xp to unlock hints or the correct solution.
And btw, this is an really easy maths question...
