Emek and Luna discovered an ancient forest path with numbered stepping stones leading to a hidden garden. Each stone showed an addition or subtraction challenge before the next step. They solved one puzzle, then checked that the answer matched the number on the next safe stone. When one answer did not fit, they looked again and found their mistake before moving on. After carefully checking every challenge, they reached the beautiful hidden garden together.
