Emek, Luna, and Pixel hurried toward a watering hole before sunset. At a fork, three trails had numbered markers. One showed 2, 4, 6, 8. Another showed 5, 10, 15, 20. The last showed 10, 20, 30, 40. Their map said to follow the trail counting by 10s. Pixel checked each pattern, and Luna chose the last trail. They followed 50 and 60 and soon reached the watering hole.
