for 1st question isn't the compiment of winning : drawing and losing ? and for the 3rd , knowing 0 is both positive and negative atthe same time shouldn't negative and non negative numbers be the correct option ? i thought compliments are kinda disjoined

Hello Aymen and André, It is interesting to ponder a bit the questions currently in the quiz. -------------------------------- Firstly, the complement of winning is indeed, as you have rightfully put it, everything that is not winning. When going over the questions offered, I suggest reading them carefully. Nevertheless, your logic is correct, so concentrate on what the task requires us to point out. -------------------------------- Secondly, I feel a small clarification concerning the whole numbers would help best. We have three types of whole numbers: negative, those strictly less than zero (x < 0) zero itself, and positive, those strictly bigger than zero (x > 0) Now, when doing complements, you need to account for having 3 different types instead of 2. Mind still, zero is neither positive nor negative. What does this imply for zero being non-positive / non-negative? ------------------------------- Finally, a new redoing of the quiz is advisable - currently there should be no problems with the answers.
