English: The 'time' block counts from 0 to 100. But now you want the 'y' position of the other arm to start at 100 and go to 0. Can you figure out a simple mathematical formula that flips the direction?
Translation: Iḥder 'akud' ad yeddu seg 0 arama d 100. Maca tura tebɣiḍ d akken adig 'y' nyiɣil-nniḍen ad yebdu seg 100 aram d 0. Tzemreḍ ad tafeḍ tanfalit n tusnakt ara yettin tanila?
