The teachers of PET challenge you to achieve a riddle. Let’s Begin… Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn’t so smart either. But now is not the time for regrets because you need to get away from these mutant zombies...fast. Can you use math to get you and your friends over the bridge before the zombies arrive? You will have to bring posible solvings to class and do not see the possible answers in the video. Are you ready? Good luck dears.
